I'm only three years older than you are. I remember clearly growing up amid a very violent society then... Vietnam, the Watts riots, the Chicago riots, desegregation, the Kent State shootings... it was a dangerous time. We live in different times now.
To share the view from the back side of the badge, I worked for San Diego PD from 1979-1990. From 1980 to 1985, SDPD officers were involved in some 140 gunfights. There were five cops killed and nine more wounded. Most of them I knew personally. Some very well. I could have been one of them very easily.
In the 1980s, Horton Plaza down town was a run-down ghetto, red light district. I worked Southeast San Diego and had to drive through downtown to get there every night. There were nights when I was half-way through my shift before I made it to my beat because of the downtown activity that happened right in front of me. There was seldom a night went by during those years when my handgun wasn't un-holstered hourly.
We could have very easily continued the siege mentality that cops had in the '70s, but we chose to reach out to the community and try to change the factors that causes violence. We were, I think, successful in many respects through the end of the 1980s and through the 1990s.
I retired three years ago from a department in the midwest. There is still violence on the streets, but it's directed in different directions. Nationally, law enforcement sees and has a very differently now than they had in the '70s. There's not nearly the random violence we saw in the '70s and '80s. The world, and the U.S. are a much different place than the insular society it was in the '70s financially, socially, and sociologically.
