Emeryville
This might be a very small city which also happens to be the home of Pixar Studios, but it is definitely not immune to crime. The chance of being killed here is way higher than almost any other city in California. Property crimes are also high. Violent crimes have started to drop since 2013, but it still relatively high. Confrontations between police officers and civilians happen all the time. You need to be really tough if you are to live in this city.
