Knocking No-Knock

Every summer it seems like the Supreme Court arrives at a couple of infuriating positions. Last year, it was Kelo and Raich, and this year they're off to a ominous start with Hudson v. Michigan, where they declared that evidence aquired in a no-knock raid can be used in trial against the defendent. Which in theory I suppose isn't completely awful, except for the fact that this is pretty much the lone means of defense we've got against discouraging aggresive police tactics. In light of the numerous innocent people who have been injured and killed (not to mention extensive property damage, which is usually uncompensated) with the paramilitary tactics favored by police these days, this is a very distressing decision. If you want to learn more about this case, Radley Balko is probably the best place to start, and you can also read some opinions here and here.
