These mistakes will never stop as long as the first choice of a search warrant is to kick in the door instead of knocking, presenting the warrant, and then if you have the right house you search every place with wall radar, and courtesy.
There needs to be a grass roots movement of all racial groups to limit no knock and after dark raids unless a police Officer is willing to swear in an affidavit he or she has SEEN the searched for Contraband in said structure.
If a snitch lies or exaggerates they should be charged as an accomplice to the police after the fact for lying.
Then if there are no drugs found the Officer is releived of duty and investigated for his truthfulness on his Affidavit.
Till then, we are all subject to being killed in our own homes for OOPS!
While many may disagree with me I can find no reason for use of Deadly Force, SWAT and heavy weapons when serving these warrants. While these Drug gangs do a good job of killing each other and their customers their danger to their neighbors is normally minimal. The do after all have families, and friends. If the cops are scared that the drugs will be put down the comode they can open the clean out and put in a screen to prevent the drugs leaving the property. It may smell bad but it will test to withing 10% accuracy in the Forensic lab.
This is the 21st Century. These police agencies can pull up a van that most own or can borrow and see everyone in the house.
Instead of 20 SWAT members rushing into the house they can do as well by surrounding the house till all heat objects are moved into the living room.
Saving money over saving lives, both LEO and Drug Dealer, needs to be the last consideration.
If big Sam is selling 5 pods of pot a week do we need a $20,000.00 SWAT action with weapons that may end up killing Sam's 14 yer old babysitter and her date over?
