Last time I've been to SF was in 2015, I get out of the BART train at Market St. early afternoon, and on the corridor to the exits there are 2 people, one lying on the floor, another shooting heroin. Out of the station, going to cross Market St. to grab something to eat, someone stops behind me while I'm waiting for the traffic light on the zebra crossing and start to scream, loud as I'd never heard someone scream in my life. Two days later I ended up inadvertently walking by Tenderloin and got fucking harassed to the point where I paced very briskly out of there. > It's not like being a tourist/visitor in Manhattan On this same trip some 2 weeks later I arrived in NYC, got to Jamaica Station from JFK to catch the metro, going upstairs on the elevators I take a round for the next flight of escalators and there's someone squatting close to the railing, taking a shit, naked, right there while dozens of people are passing by. Later in Manhattan I'm staying in Hell's Kitchen, very close to PABT, a guy tries to mug me when I'm going to a 7-11, I get away from the attempt just to get to a corner store and see a fight breaking out... Just giving some anecdotes of just one of the trips I made to the USA, I had many other odd encounters during other trips, I have never experienced much of that (apart from the mugging when I still lived in Brazil) in other parts of the world I've lived at or traveled to.
