Being homeless, mentally ill, or a substance user does not give anyone the right to defile public or private property. 

Furthermore, being a chronic abuser of any of those three classes should not be easy. Giving hand-outs to these repeating offenders does nothing but further enable their inappropriate societal behavior. If they choose the "homeless lifestyle" to get back at Daddy, or prove to whoever they are somehow enlightened, they really should I form a co-op with others who share those beliefs, purchase their own property, and destroy and harass people to their heart's content.
