Sure - "'Out of control': Organized crime drives S.F. shoplifting, closing 17 Walgreens in five years"

If you haven't been seeing this you haven't been watching. It's absolutely brazen - daylight robbery literally - and turns the store workers and folks shopping into cynics.
Chelsea (new DA) took office end of 2019 or early 2020. That really marked a major change.

You probably don't realize how much crime is simply unreported - it's a massive amount. Go to any car glass shop - they will tell you how "crime free" SF is.
Note that I grew up in an actual low crime city. That means I never had a house key, we never locked the house. We left the keys in our cars. This isn't out in the middle of no where, this was a city (with very low crime).
You say your children can walk to neighbors freely like children can in east bay? You are the exception in SF.
I realized that folks in the city are just so used to crime, to the steps you have to take to avoid it, they don't realize the impact it has on their quality of life. You really don't get to know your neighbors that well (relative to a totally safe neighborhood where everyone is more welcoming). This last bit is anecdotal, but neighbors really look out for each other outside SF. Folks do the block email lists, get togethers.
I did a quick comparison to Lafayette in east bay.
San Francisco 2019 Murders (which was a low) - 4.5 murders per 100K. Lafayette - 0.0 per 100K. Robberies SF - 344 per 100K. Lafayette 11 per 100K. Lafayette had 3 robberies in the entire year. The differences are likely larger as in SF there are so many robberies per day that a fair number just don't get reported, especially in some parts of town where cops are not liked - folks are not calling it all in.
