We the public have absolutely no eyes on the inside. We have no idea what is being taught to these thugs or who is doing the teaching? I think we would all be very surprised to find out that they are being trained to shoot the dogs, grandpa's, flash bang baby cribs, act on warrants only after midnight, battering ram front doors, curse, swear, and threaten families and children while handcuffed on the floor, and lots of other root cause behavior.
The one thing I noticed in that video is that they were horribly exposed to being blindsided. If that public decided to act on the assault, the cops would have never known what hit them. Good thing it wasn't near the baseball bats in the sporting goods department!
I've chewed out several of the local constabulary when they had their heads in their computer/phone and I walked up on them and they didn't notice.
I walked away and made noise to attract their attention and then 'splained, but yes, the lack of situational awareness is sad. I won't allow it in my grandsons.
