Here's a related story..
An acquaintance of mine (female) was mugged a long time ago. As she was walking along, some jerk passed by, turned around, and snatched her purse. Only problem was that her purse strap caught on to her arm. Now she and the jerk are struggling. He's pulling on the purse, and she's trying to free herself and let him have the purse. She fell to the ground, and the guy gave up and took off.
All this during broad daylight. With plenty of people around. Standing by and watching. Nobody offered to help. Nobody called the cops. Why? She happened to be in a neighborhood of mostly Latino immigrants. They simply didn't want to get involved. Either they have a fear/distrust of cops because of a corrupt legal system back home. Or they are in the country illegally and don't want to risk getting deported.
Lessons here: Don't expect anyone to help you if you're in trouble. And always be aware of your surroundings. Male, female, gay, straight.. it doesn't matter who you are or where you are. It can happen. He live in strange times. And lots of people out there have this weird pent up aggression just waiting to be released on someone that is perceived to be an easy target.
Stay safe and look out for others.
