I agree use of these warrants needs to be very limited. The first reaction of many homeowners on being invaded without warning is to defend oneself.
There's an element of shock as well. You've got a split instant to commit yourself, either to passivity or resistance, which isn't enough for rational consideration.
The no-knock warrant was all based on lies that an HPD officer apparently wrote.
In an affidavit, you swear under penalty of perjury that the facts you set out in the document are true to the best of your knowledge. Submitting a false affidavit is perjury, and a felony. When people are killed in the commission of a felony, the person responsible is usually charged for those murders. What better warning to cops that they must not ever file a false affidavit than to charge this scumbag with murder?
"No knock" raids have no place in a free society. Every home invasion begins with a kicked-in door and shouts of "Police! Everybody on the ground!" and the homeowner has a split second to guess who is storming his castle. If he defends his family against the police, he will be executed. If he fails to defend his family against the hoodrats, they all may die. Why is this ever necessary?
I want to know what the cop had against the people he had taken out. He planned this. It was a planned murder. How many other times has he done this?
