IJ, you've got a very tough road to hoe. pertaining specifically to this park, it's going to be bum guarded very well. the overall perception of bums is at best that they are the same as those people who come knocking on your door trying to get you to read scripture, or join their church. a minor inconvenience that people sneer at. some would say it's more annoying, some would say less. I can choose not to answer my door when they knock, I can open the door and confront them (going by the theory that being of some faith they would generally choose to turn the other cheek than engage in a confrontation), on the street I can ignore them, but they can persist, I can also confront them, but who know how they would respond. That the best perception that they would be offered. typically though, people perceive them all to be thieves and drug addicts, and they'd just as quickly stab you as ask you for change. I'd say that it's probably somewhere in the middle. It's doubtful they'd randomly attack someone without being confronted, but if you think that they won't commit crimes of convenience, I think you're wrong. Park your car on a side street in midtown where there won't be much traffic, and make sure there's a loose rock sitting next to your car and just a single flashlight sitting in the center console where it can easily be seen. most times when you return to your car, the rock won't be sitting in a pool of broken glass, and the flashlight won't be missing, but it will happen, and I'd bet if you had a video feed, you'd see a homeless person walking away from your car with a new prize in hand. It doesn't help that a very good portion of the homeless are homeless because they have mental health issues and no one cares enough about them to take care of them correctly.
