I watched it on a big screen, and I can't tell you how frothing mad it made me.
The police engineered a situation that allowed them to shoot the dog. They also let the dog bleed out in pain while keeping it's owner away and unable to provide any comfort to the poor thing.
To push me further along the "*expletive deleted*ck all law enforcement" path, none of the other officers there even offered a "WTF?" to trigger happy Barney. They were all like "shrug, I guess that dog is going to die." If 99% of cops really were good, that they would refuse to work with or near this supposedly rare trigger happy bad apples.
I thought all day about this after watching the video in the morning, and the nicest thing I can come up with is if that officer comes out of his house one day and eats a 5.56 round on his porch, I'd consider it just.
