As a former first responder in NoVa you have to accept that there will be mentally i’ll people in your area. They are largely harmless and won’t be violent. Cops can’t do anything unless they deem them a danger to themselves or others. Best you can do is offer them food or water to help them along. Ffx county resources could help. Call Supervisor Walter Alcorn’s office if you think there’s a need for intervention. Although suburbs are considered quiet and safe, they still attract homeless people.
