“Slobber the boot harder, you can’t.”
What is your source for what you claimed about the officer’s past misconduct?
Even if those allegations are true, they are irrelevant to this situation where everything was done by the book. The SWAT Team was executing a legal warrant to gather evidence against a dangerous individual hence the no-knock warrant. Upon entering the room the cops loudly announced their presence and instructed the person on the couch to show his hands. It is a fact that Mr. Locke lifted the weapon in the direction of the officers. It was reasonable that he was shot because of that fact, case closed.
No bootlicking is needed to see that the shooting was justified in this situation.
