He probably arrested an illegal.
It is probably the most liberal department in the US, but that never satisfies the left.
From the Christian Science Monitor: “In January, Chief Suhr announced all police would annually pledge to avoid hate, bigotry, and intolerance and report any instances they encountered.”
So, the department genuflected to the left, and of course it wasn’t enough. Crime is very bad up there because police are afraid to arrest anyone. Even the lefty residents up there are complaining about the epidemic of burglaries (while wondering what they did to deserve it).
Bottom line: Left fighting for total surrender of department to the Marxists who run the place.
