Some have increased while other have decreased. The total number of crimes have increased by my own experience. Many of the crimes are not reported. It is the experience of other residents as well [8]. For example, my experience is that car window breaking has increased dramatically. I did not have any car window breaking in the first 5 years in SF (I live in a relatively safer neighborhood). This year, my window was smashed. I see glasses all over the streets nowadays. I did bother to report to the police because i did not think the police would be able to do something about it.
Anyway, as a mayor, if London Breed promised to do something and she did not, it is a sign of incompetency. It erodes her own credibility.
