I have walked through the plaza every day on my way to work in the mornings. I have encountered the same homeless people who were there before the plaza ever even existed. I don't think it's drawing a whole new crowd. I do think it is wrong to blame the plaza, "Green People" (whoever they are, martians maybe?) and Danny Dromm for a problem that has existed in that area for YEARS.
The major problem with that area is no one seems to really care for, or take care of it. The merchants there seem to have little interest in the greater community they ARE a part of (even before the plaza) and couldn't be bothered to do more than the minimum amount of cleaning and tending to their area. The one thing places like Times Square, and other places in the city have that make them go a long way to working is a Business Improvement District. With a BID looking after things like security and sanitation it makes a huge difference. However, I'm not sure the property owners in that area are willing support this (why we should continue to support them is beyond me). Maybe rather than complaining and blaming we should be asking our elected officials how we can help make something like this happen.
I also think it's important for those of us who live here to put as much pressure as we can on the Police Department. I think there are monthly meetings where the community can let the police know what their needs are and what's going on. It is a lot more work than any of us should have to do, I know the last thing I want to do after a long day of work is attend yet another meeting. But sadly, that's they way things get done.
In addition to BID's many neighborhoods that we cite as being better off than poor old JH have a VERY active community base. People who step in where the city fails and take action to make changes. While that's often ascribed to more affluent communities there's no reason it can't be done here. There are quite a few neighborhood groups already doing this work volunteering now and then getting more connected and productively working towards solutions to problems seems like the right course of action to me.
There are also homeless outreach organizations and churches that will come and try to get people off the streets. It's very very hard work. Supporting their efforts here could help the problem in due time.
As far as safety goes, no one should feel unsafe, especially in broad day light on their way to work. Maybe walking to work with a neighbor or two would help, there is safety in numbers.
My point is it takes a lot to keep a community together, safe and prosperous and that means those of us that live here have to do a little more than any of us would like to achieve the sort of community we want to live in.
