I can’t don’t know about drug sales, but I speak to people who have all the other atributes on a weekly basis as a triage interviewer for a food/clothing bank. By and large, they are a lazy, pathetic, “gimmee ma stuf” type people.
They will be dangerous when the riots start.
Only to themselves.
And then only as long as they can find food and water and stay warm......and don't run afoul of me or mine.
Not for long, in Texas.
