Sounds good, but what if the violent felon is around people who aren't aware of said felony.
Yes, that was what happened to Amir Locke. He was not the target, but pulling the gun on the police led to him being shot.
Or Alteria Woods. She wasn't the target. Her boyfriend's father was. And while he was captured without harm, his son decided to shoot at cops who returned fire.
Obviously, it is impossible to cover all contingencies. Sometimes bad things happen.
I must note though that in the Donovan Lewis case, uninvolved occupants were not harmed.
No knocks while successful some times are dangerous and have caused the death of innocent people at other times.
This was not a no-knock warrant service though.
I think no knock warrants, while they should not be routine, serve a legitimate purpose and therefore should not be categorically banned either.
The real question here is, are you ok with innocent civilians losing their lives at the expense of capturing felons?
Obviously, care should be taken that innocent civilians are not put in undue risk. But zero risk is impossible without giving up on capturing dangerous felons. And I do not think that's a good tradeoff.
Also, there is this saying "lie with dogs and you wake up with fleas". Amir likely knew that his cousin was in some bad shit. Alteria must have known too - the whole Coffee family has a long history of violent crime.
The question is not directed at you per say (because I already know you're ok with it by how you reacted to Amir Locke who had a license and permit for the gun the police shot him under 10 seconds over).
He had no permit to point the piece at the cops. It was reckless to handle the weapon while not fully awake, and he unfortunately paid with his life for that recklessness. I am not happy he is dead, but I neither think any of the police did anything wrong (much less criminal) nor do I think police should stop serving warrants on murder suspect because their cousins might be sleeping with a gat.
Edit: Disclaimer. It can easily happen to me, because I'm around a lot of questionable people due to the nature of what I try to do for my immediate community. I imagine some folks might think "well don't be around felons" is an excuse for police to shoot me during a no knock raid but then people need to cut the crap on complaints about black folks like myself not trying to get our shit together.
Yes, being around felons does put you at a higher risk. Probably far more risk from those felons' rivals (think drivebys) than from police serving warrants though, even if the latter is not negligible in itself.
That said, no knock warrants are a minority of warrant services. Most are like that of Donovan Lewis, where police knock for an extended time (>5min) if needed. And unfortunately, even knock warrants can be deadly.
Now, why can police be so jumpy when warrants are served? Because warrant service can be very dangerous for the police. This happened just a couple of days ago in my neck of the woods.
2 in custody after 2 deputies shot, killed in Cobb County
The officer who shot Lewis probably acted out of fear that this might have been him.
