This took place in West Sacramento, a smaller town just on the western side of the Sacramento River. They've been having some serious problems with gangs recently. Similar gang violence is occuring in south Sacramento, although no passenger trains run thru that part of town. Infact, a large mall was recently demolished because people were afraid to go there because of the violence and crime in the area.
What a shame.
I was in Sacramento, oh, 20 or so years ago.
It was lovely.
