I grew up in Tacoma.
The old rule was that the cops wouldn't enter Hilltop, Southeast side, or Salishan section until the shooting stopped. -That kinda leaves the civilians to protect themselves. When thugs were encountered, Tacoma cops got a bad reputation for shooting first, then asking questions.
I never lived "in" that area, but there are places I would have to travel to/through throughout the Tacoma/Seattle area that kept me on my toes. Thankfully I chose long ago to disassociate myself from home as I knew it and moved to rural locations some 75-100 miles from the metropolis. No, that wasn't Detroit or L.A. but gang activity was/is there.
Living in a rural farm community right close to our U.S. border, there are ethnic transients for crop harvest and such. Some of them stay. Unfortunately some of the bad have stayed. I am convinced that there's gang activity everywhere. Maybe not to the same scale as where there's more turf or 'business' competition, but being a border town, there's plenty of drug trafficking going on. That almost always invites more gang and organized crime. It doesn't take a long drive to find graphiti on the side of a barn, business, or railroad car. Is all graphiti from gang activity? Probably not, but there's enough to figure that someone's staking claim. Enough that the county has a gang task force within the Sheriff's unit. It's not just kids. There's a local biker club with international ties that's got a less than favorable history too. Not too far away there are some European immigrant communities. It doesn't take a long listen to the police scanner or read of the local newspaper police blotter to figure out where there's organized crime.
Still, I know that half our town doesn't lock the doors. Almost a Mayberry type town. Most everyone knows everyone. There are 39 churches in town. Only five liquor serving establishments. No alcohol served after 12:01am Sunday until Monday morning. Generations of families living within ten square miles of each other. It's pretty nice to live here without fear.
