Yes, at the neighborhood level. One property owner on our street decided to partake of the benefits of leasing his property to be used for Section 13 purposes -- welfare.
Long story short...the mother and her children brought gangs to our street, her children ran wild, and we the neighbors were feeding her children, watching over them and protecting ourselves (and each other) from the negative side effects of their "culture". The socialist theory had been that if a Section 13 household was placed on a good street, the effects would "rub off" on the family in need of cultural redirection. HA!
As a result, we all went after the property owner who had plagued us with such a problem, and we each vowed to each other to never sic such a nasty trick on each other should we move or sell. To date, the folks back home tell me, it still holds.
Had this problem in one neighborhood. Every time the police came or my sleep was disrupted, I called the landlord. Right after I called the police. So did the rest of the neighborhood. I always said. YOur tenent’s behavior has woken me up, so I decided you should join me.
I let the police set up survailence in one of the apartments.
Tenants were relocated with in a month....a number of them to jail.
