cop was in his legal right 100%... but in my opinion... i think YOU SHOOT SOMEONE OR SOMETHING when it endangers your life... I dont think this dog had life threatening danger towards this cop. I think there could have been a dozen of other ways to stop the dog... maybe TASER??? or idk...
So you are telling me that if a dog charges you and you have a weapon you are gonna try something else first? Seriously? That officer had NO WAY of knowing if that dog was gonna sink its teeth into him and rip him apart. He could have been seriously injured. His actions were totally the correct ones.
