Before the city built like crazy in the 2000's, Roseville, Ca. was a small, quiet town with very little crime.

I lived there for 2 1/2 years and never had a problem except when 2 8 year old kids broke into our rented house, stole from us, trashed the house and killed 2 of my beloved cats by throwing them over a fence where a rotweiler killed them after they cornered them.
We called for days for those cats and cried a lot and could not understand why they were not coming home.
They climbed into the house through the cat door and jimmied the lock to the inside of the house and lived next door to us and their mother was a welfare Mom and alcoholic.
It took me a year of fighting with the DA. the Mayor and the police to find out WHO did it.
I was told they had to protect the "rights" of the children.
But we had no rights to protection and neither did our landlord who was furious that he had to repair the damage done in the space of 2 hours when we were moving out.
I never forgave city authorities for that.
And never will.

Maybe this is another effect of how Northern Califormia has gone all to hell in 35 years since I lived there.
The Roseville Police Department is hiring armed guards to help patrol in downtown. The guards are there to help keep things safe and crackdown on parking problems.
