@OmSigDAVID,
When I travel (which is frequently), I "case" all manners of neighborhoods by walking. I like to look at buildings (architecture), the people, and how they live. That's whether I'm in the US or in third world countries. I have never worn a hoodie, but I do pack a backpack once in awhile.
According to the Zimmerman apologists (including you), I'm a potential robber.
I'm not in need to steal from anyone; we have enough cash to buy what we want.
Even skittles and a soft drink.
