I can't find the stat, but it was in an SF Chronicle article on police not doing anything about a homeless person tearing down a parklet, but in San Francisco, the number of traffic violations ticketed has gone from 10K+ to <1K in the same period... it is really astonishing how lax it has become and it looks like traffic and property crime is the least enforced.
