Warning:Warning:Warning

The level of danger in San Francisco is a lot higher, since the last election.

Reason's: (just my opinion)
The District Attorney is not prosecuting anyone.
this includes rogue cops, cop killers, drug dealers, and the other criminal elements.
Care-Not-Cash implemented by Gavin Newsom has made the majority of homeless more desperate and willing to committ crimes.
Office of Citizen Complaints has become useless and biased.

What to do:
Arm yourselves or move away.
Secure your apartment (lock all doors and windows at all times).
Install surveillance cameras if possible.
