Armed cops kicking in doors unannounced to conduct no-knock searches have been known to make mistakes, to kick in the wrong door.
Armed home invaders have been known to kick in doors and scream 'Police!' to deceive their victims into disarming themselves and becoming completely compliant.
Armed home invaders have been know to summarily execute their victims after burglarizing their homes and perhaps raping them.
In my opinion, no-knock searches like this one put the public in much greater danger than the drugs the cops are after.
This is gravely stupid, heavy-handed police work.
I agree that no-knock raids need to have specific parameters and some might be too quick to use them where they are not necessary. However, the answer to that problem is working within the law to establish clear guidelines when and in what situations such a warrant will be issued.
Regardless, in this situation, the officers were acting with a warrant, issued on probable cause, signed by a detached neutral magistrate.
Nobody wants to place any blame on the worthless doper in this case, who brought the problem on himself, both by selling drugs, and then by bringing a golf club to a gun fight.
