Yeah. A jury's going to take the side of a bunch of scummy meth dealers when they kill a cop.
Are you high?
Yes, they will--at least sometimes. I would, almost without exception. And then there's those cases where the cops get the wrong house.
And what about when the police make a mistake and go into the wrong address?
It happens, not nearly as often as some would like to make out, but it happens.
Does his argument hold any water then?
It won't always be "scummy meth dealers".
It might be someone with something that was perfectly legal and reasonable, then suddenly redefined as illegal (as the BATFE has been doing lately).
It might be the neighbors of the "scummy meth dealers", invaded without warrant because the wrong house was targeted.
It might be someone who would cooperate when polite social procedure is followed, and who would fight when unknown invaders come crashing thru his door at 4AM.
Yes, the cops - with warrant - have a legal and constitutional approval to enter & search without being polite & patient. The occupants also have the right to act appropriately when strangers burst in unannounced without apparent cause. The two issues are not incompatible.
If it could be proven that the occupants of the house shot a police officer who did not announce himself before breaking down the door, I'd have a hard time voting for a conviction.
