The local crime statistics are saying that San Francisco is a safe city with crime trending downwards.
The result was no one was investigating or prosecuting crimes anymore. Everyone predicted what would happen next is that the pundits, the news media, and the politicians would point to "see crime is actually trending downwards the numbers are going down." when in reality police were no longer as responsive, at the same time people would stop calling the police because the wait times would be too long and they know nothing would happen.
This is what's happening, and I will not be convinced otherwise. 2+2=4
