On balance Paul MIGHT be right. There have been more than a few tragedy’s from these things. Yes it gives the bad guys a chance to dump some small amounts of drugs but too may have gotten killed when the cops got the wrong house. On the other hand they prevent an armed standoff or hostage set up. So it is a tough call.
Except those armed standoffs and hostage set up almost never happen. It’s not a tough call at all. The fact that they so regularly get the address wrong is why no knock raids need to be banned. And a million other reasons. They are simply morally wrong, and stupid, and much higher risk for everybody.
Which is the dirty lie they tell
Coos wilk say its gives the Perot time to dump evidence.
Uhmmm, who GAF?
You are there executing a warrant on a probable case so, be done with it, unless your real goal is to exercise your testosterone.
