I really do not understand what your point is and I fear that it would be a long, long hashing out process to get my point across, one I am not keen to enter into for a variety of reasons, chief of which is that it sounds like you are justifying the bias against homeless and refugees, so this is likely to be an uphill battle that makes me look bad no matter how I handle it.<p>Suffice it to say I stand by the assertion I have already made at least twice: Dealing with security concerns of all involved parties will be a make-or-break detail for such a project. The specific concerns each side has may differ, but you need to look at making sure everyone is equally protected or this has disaster written all over it.
