I don't trust the statistics for lesser crimes because so many of the victims never file a report. In many cities the police now subtly discourage people from filing reports because they don't want to deal with the paperwork or have their statistics look bad. But I think we can generally use the murder rate as a proxy for the overall level of criminality.
I watched it start in the downtown area and then spread into residential neighborhoods, and the homeless/criminal element become more physically aggressive too. "Public Intoxication" also increased except instead of drunks it was fentanyl users.
Car crimes similarly went from simple opening of unlocked doors, to smashing of windows to grab bags or cutting out catalytic converters.
Public transit went from bearable to unusable (though this might be better now, I don't have firsthand knowledge anymore since I stopped using it during the decline).
