A childhood friend's dad was a cop for 25 years; retired in the mid-90s. He never shot his gun, and only unholstered
once in his entire cop career. My friend followed his dad, also became a cop in the exact same district; he's getting ready to retire. He's unholstered his gun
countless times. He says he's shot at numerous people in his career, and even killed one dude. I once asked him what the difference was between his career and his dad's. He said crime was actually worse when his dad was a cop, a lot worse. But the big difference was the public's attitude and his training. He said the public had accepted the "tough on crime" narrative; that wasn't the case in his dad's days. But also, the training was straight-up military. He said that if he didn't use the military-style tactics, he would be sunned by his peers and even reprimanded. He said the training repeated one narrative, over and over: "It's us versus them."
He told me a story about a noise complaint. He said him and his partner banged on the front door of the house, but there was no response. He said they called in the status, but were told to wait. About 10 minutes later multiple SWAT vehicles arrived. He said one of the vehicles literally drove into the side of the house, making a huge hole in the house. About a dozen SWAT officers ran into the house, multiple shots were fired, the tear gas started a fire. The house was absolutely destroyed. ... No one was home; the house was empty. A kid left the TV on really loud when he left for school. A neighbor called it in, hoping the cops could just go into the house and turn off the TV. Worse, there was no punishment to anyone involved; the cops were doing as they were trained.
