Basically, you're screwed.

Reason Magazine - Hit & Run > Ryan Frederick's Preliminary Hearing:

"Pay close attention to this one: According to a reporter I spoke with this evening who attended the hearing, Detective Kelly Roberts testified that the police announced themselves four times, waiting four seconds between announcements...

After the fourth announcement (presumably, about sixteen seconds), they detected movement in the house. Roberts says a light "changed." It was at this point that they announced "Eight ball! Eight Ball!" a code signaling that the raid had been compromised. At that cue (pardon the billiards pun), they took down the door with the battering ram.Think about the implication, here. The police come to Frederick's home to serve a knock and announce search warrant. He's asleep in his bed. Sixteen seconds after the first knock, it isn't the fact that he hasn't yet come to the door that triggers the violent, forced entry. It's that there is a "change" in the light. It's the light that makes them conclude the raid had been compromised. Not the flush of a toilet, or the cock of a shotgun. A light. How do they know that light isn't someone coming to answer the door, possibly to allow the police to come in for a peaceful search?

What this means is that, as I've written before, there's no real difference between a no-knock and a knock and announce warrant. Once the warrant has been issued your door is coming down, and there's not much you can do about it.

This then raises the question of what exactly you're supposed to do when someone knocks on your door, and announces that they're the police and that they have a search warrant. Don't come to the door, and they're going to break it down and come after you. Come to the door to verify it's really the police (by no means a given)—and to let them in if it is—and your very movement toward the door can, also, be a trigger to break the door down and storm your home. Arm yourself and wait for them to come in? You're practically begging them to shoot you.

Seems your only option is stand somewhere in your own house with your hands in the air, wait for the door to come down, and hope the raiding officers don't mistake your t-shirt for a gun, or possibly trip or mistakenly fire and accidentally kill you. Be prepared to be thrown to the ground, stepped on, handcuffed, and have the barrel of a gun pointed at the back of your head.

This is just one of many conundrums posed by the proliferation of paramilitary-style police raids. The people on the receiving end of the raids are put in positions where it's nearly impossible to even know what the right response is, much less be in a position to make it. Not to mention that, at the same time, they're being subjected to trauma that makes any sort of clear-headedness or careful consideration of their options pretty much impossible. Make the wrong decision and you're either dead or facing a felony charge."
