Act vs. Rule
I'm writing this as someone who has never had a graduate-level course that systematically dealt with normative ethics, so maybe this is all well-tread ground, but since I'm going to be teaching a 300-level ethical theory course for the first time I need to work through some of my thoughts on some issues, and I'd like feedback on some of my initial thoughts on a few matters. The first one is that the act/rule distinction often used to protect ethical theories from standard objections is a complete mistake. One problem utilitarians face is that many counterexamples seem to show that utilitarianism gives the wrong result. Torturing one person excruciatingly for the sake of everyone else's happiness seems to be the right thing to do. Sliders had an episode that explored this. The town they ended up in had a creature living underground that fed on human beings, slowly killing them in a very painful way. It had an agreement with the townsfolk that if they would give it regular victims, it would produce a substance for them that would extend their life tremendously and give them excellent health for the rest of their lives. The town was peaceful and seemed like a utopia. The sliders arrived through the interdimensional gateway to discover that even they were affected by something that gave them such happiness that they weren't suspicious at all until they discovered someone missing. This example seemed to me to be exactly what critics of utilitarianism are getting at when they say it requires people to be used as a means to the end of the others, and even when it's only one person compared to a great many it seems to be a violation of that person's rights.
Another example is the famous race riot one in the ethics literature. I don't remember offhand who first produced it, but I've found it in most introductory ethics texts. To appease the mob, who will begin lyching people and rioting, the sheriff decides to save a lot of effort and just put an innocent man to death. Since all they know is that the rapist in question was black, they just find a black man and kill him. Utilitarians should say that this is the right thing to do, because it only costs one many his life and prevents much worse harm. Yet it just seems unjust and a violation of this man's rights. People standardly give such arguments against utilitarianism, and I've seen two sorts of responses. One is simply to bite the bullet and say that we really just have poor intuitions on these cases, and it really is the right thing to do to use that one person as a means to the greater end. Some utilitarians have done this. The other response is to revise the whole theory. It's not about what acts in particular lead to the best consequences in terms of happiness and unhappiness (or substitute your own intrinsic goods if you want to expand this to a more general consequentialism). The original theory put it that way, but what we really ought to do is look at which types of act will tend to produce good results. Killing innocent people tends to produce bad results, so we shouldn't do it. Torturing innocent people for the sake of others' happiness tends to produce bad results so we shouldn't do it. Then you come up with a whole list of rules and pick the ones that maximize happiness. It gets you out of the problems I've been talking about, because you now no longer get the counterintuitive result. I have two problems with this. First, it seems to do as much damage as it saves. Second, it isn't at all clear what this is supposed to look like, because rules turn out to operate on a continuum from very specific rules to more general rules. It causes as much damage at is saves for the very reasons that utilitarianism is supposed to do better than theories like Kant's when Kant's absolutism seems wrongheaded. Lying, for instance, seems generally wrong when it comes to hiding something you did wrong, deceiving someone for personal gain, or trying to make someone else look worse than they really are. On the other hand, it seems pretty clear to most people that lying is ok when the person being deceived is trying to harm someone, and a lie is the only way to protect the potential victim. Lying to Nazis hunting Jews during the Holocaust is a common example along these lines. Similar examples for breaking promises show up in all the introductory texts. If you promised someone to meet them at a certain time, but it turns out someone will die if you don't break that promise, you don't have any moral obligation to keep it. Utilitarians get the right result on these cases, mostly because they focus in on the act rather than the rule. Kant has an absolute rule against lying and breaking promises, but if you modify the view to make it not about the absolute rule but about evaluating whether a specific action will be universalizable, then you might well end up with a non-absolutist neo-Kantian who says lying or breaking promises is ok in such circumstances as the ones I gave. This comes from having an act-based Kantianism rather the rule-based one Kant himself developed. So it turns out that act-based ethical theories do better with some cases, even as rule-based ones do better with others. How will utilitarianism avoid the problems facing theories like Kant's if they make their rules so general as to include rules against lying and promise-keeping on the grounds that those actions tend to produce unhappiness? Similarly, how does the neo-Kantian avoid the problems with consequentialism if she drops the absolutism and then says to universalize particular actions to see if you would want everyone doing that action in only that kind of circumstance? The "means to end" restriction seems to prevent doing this in the cases of the racist mob and the torturing case, because both involve using someone as a means to an end. The problem seems to me to be that once you go to act-deontology you have to drop the means-to-end prohibition, since that's now got to be applied on a case-by-case basis. The only way out I can think of is recognize that rules can be very specific or more general. If you can resist making your rules too general, they avoid the absolutism of Kant. On the other hand, if you can resist making your rules too specific, they avoid the extremes of act-utilitarianism. Yet this seems to raise so many problems that I'm not even sure where to begin figuring out how to resolve them. Any time you get a difference of degree that makes a huge difference in a theory from extreme to extreme, just saying that we need a via media doesn't solve anything. Maybe the realm of normative ethics has done this and I'm just unfamiliar with the literature on this point, but we need to see how the theory will figure out where to settle on that continuum between very specific and very general rules. I'm skeptical whether there's one place that will solve all the problems of the two extremes. It may well be that settling somewhere will solve some of the problems but not others. I'd have to see this worked out in detail to have those doubts assuaged. Another problem is that I can't even think of how you would explicate such a view. How do you rigorously define how specific your rules need to be? Is there such a way? Putting in hard and fast rules about how general a moral statement needs to be just seems to me to move in the wrong direction in terms of capturing our moral intuitions, which is what many seem to see the process of ethical theorizing. Maybe some will insist that you can't get such a theory, but this seems to me to be giving up the very idea of having an ethical theory. If you're doing that as a way to move toward a virtue conception of ethics, that's fine, as long as you are admitting that your move will bring you into ground that will not involve a complete theory about why certain actions are right and wrong. Some virtue ethicists embrace this lack of theory, but others really worry about it (or at least should given that they think they have a theory). As far as I know, Linda Zagzebski is one of the few contemporary virtue ethicists to try to develop of genuine virtue theory that covers such things, but I haven't gotten far enough into her book to know if she succeeds. These are just thoughts I've had as a metaphysician having to teach this stuff without having had graduate courses that deal with it systematically, so I'd welcome comments from anyone more well-versed with the literature on how people who really do this stuff try to avoid the problems I've raised. I'd be very surprised if these problems have never come up in the literature. Either way, I welcome suggestions on how consequentialists or Kantians can still make use of the act-rule distinction to steer clear of counterexamples. I'm not arguing that the distinction isn't important, just that it doesn't seem to solve the problems it's supposed to solve.

Comments
I'm not at all well-versed in the literature, but I'll comment anyway...
I'd add that if you don't put a limit on how specific the rules can be, that would soon collapse into act utilitarianism. After all, the "rules" that would maximise happiness are surely provided by the 'greedy algorithm' of maximising the utility of every individual act.
I think Desire Utilitarianism provides us with a nice way around this problem. That is, we replace 'rule' with 'desire'. Roughly put, a good act is that which a person with utility-maximising desires would perform.
From the viewpoint of belief-desire psychology, Act utilitarianism is a psychological impossibility. People act based on their desires, and these desires are persistent (and, for the most part, fairly 'general') entities.
This explains why the sherriff shouldn't frame an innocent man, even though it would seem to maximise utility if considered in isolation. Fact is, if you have the sorts of unscrupulous desires which would allow you to act suchly here, those very same desires would likely cause you to act in terrible (utility thwarting) ways in other situations.
So we can avoid the typical objections to (act) utilitarianism. Does this then lead us into absolutism?
Not at all - because desires, by their very nature, aren't absolute in the way that rules are. They come in different strengths, and when they come into conflict (as they inevitably do), the stronger desire wins out. So even though we should all have an aversion to lying, we should have an even stronger aversion to letting innocent people get hurt or killed. (And this explains why we should lie to the Nazis.)
So this way, we get the best of both worlds :)

Actually, that was one of the points I was going to make, but I guess somehow when I looked over it to see if I said everything I didn't notice that it wasn't in there. Thanks for pointing it out.
I'm not familiar with desire utilitarianism. I'll have to think about it more before commenting.

I think you're right that one motivation for rule-consequentialism is supposed to be that strict adherence to act-consequentialism will result in bad things happening.
I think your first worry can be handled by incorperating a 'prevent disaster' rule. Such a rule would override other moral rules, if following the other rule would result in disaster. If not lying to the Nazi soldier will result in innocent people being killed, then that's a disaster and one ought not follow the 'do not lie' rule. Notice that this doesn't mean that our rule-consequentialism collapses into act-consequentialism. Act-consequentialism holds that we should lie whenever doing so will produce more good. The disaster clause doesn't tell us that. It only says to break the rule whenever there is a sufficiently large difference in the value of expected outcomes.
A step towards a solution to your second worry is the fact that there cannot be too many rules for us to remember--we're cognitively limited--so the rules cannot be too specific.
By the way, act-consequentialism might be formulated as a rule-consequentialism with just one rule 'maximize the good'. That's quite a general rule.
Brad Hooker's "Ideal Code, Real World" (2000) seems to offer a good formulation of rule-consequentialism.
