You did the right thing; always trust your instincts.

I live across the street from what I refer to as one of Seattle's Permanent Floating Crack Dealerships; there are evenings I'm willing to walk to the store two blocks away, and others when I'm not, and the same number of unsavory-appearing people will be there each time, it's just a feeling.

Take care, and give yourself credit for doing the right thing.

And not racist; the... projected menace? from him had nothing to do with his color, everything to do with who/what he is or intends.

All this is my opionion, of course...
