I Guess you must not be riding it as much as you think you do. I’m an infrequent rider and I’ve seen 2 altercations and multiple (10+) disturbances since January.
The funniest (or not if you’re not from SF) was a guy boarding a full bus with a 7 foot long dining table with the legs attached, arguing and threatening anyone who protested. Eventually he dropped the thing on someone’s foot and starting an altercation which delayed everyone by 15 mins.
I've ridden the 22 through the Mission at midnight every Tuesday for much of the last seven years. I assure you that's exactly as much as I thought I do.
You might be magic. Crazy, crazy shit goes down on Muni. I used it to commute from outer Richmond to downtown for years and the bystander effect was fully powered up on many of those rides. And it wasn't always the homeless people, little old Asian ladies could be hella scary.
I might be. I also commuted downtown from the outer Richmond for years, on the 31, the 38, the 1, and the 5. Oh, I've seen plenty of crazy stuff, but only one assault.
Okay, the point I think the poster up there was trying to make is that there are degrees of assault. I never saw anyone murdered, and only twice some sort of physical struggle. The number of times crazy yelling broke out is uncountable by me, though.
