Eghad, my ex got into a potential situation at the changing house at a public beach. Some dirtbag was beating and choking his girlfriend. My ex intervened, all 5'3" of her, in a bikini.
Should she have avoided a public beach, in broad daylight?
Or perhaps she should have just not gotten involved...
As I noted earlier, I had another confrontation outside the Federal building, in view of the front doors, in a downtown area. Another domestic violence case, as it turned out, although at first I thought it was a mugging.
My point is, it's fine to avoid known problem, or even likely problem areas. But if you think that nothing will ever happen because you only go to "nice" areas, you may find yourself getting some nasty surprises.
