Yeah it is. There was a guy trying to break into the cars when my mother in law came out to visit and we took her out for pasta - cop car literally casing the lot where we were, then her and my family went to SF for a visit and she had to call the police because there was a guy actively casing cars.

Got our bikes stolen after leaving them out in silicon valley too inside of a very upscale walled off apartment complex. Took me by surprise because we live in a nice area.

I've had a lot of different first hand experiences that have made me extremely weary.
