I have walked around my city in the US for decades and can count on one hand the number of times, I have seen crime happen live and in person on our streets. In a recent single trip to SF that was just a few days, I can say I saw perhaps a half dozen active crimes. Also of note, i have seen public urination only once here, but saw it twice in between the airport and my hotel in SF.
Live where ya want and how you want, but let’s not pretend SF is no different than other places in the US. It is, and frankly it’s shocking and blows my mind that people pretend it’s normal.
