You can call it racial profiling but better safe then sorry these days. We read about crazy **** everyday going on in this world so people need to keep their heads up. If I had to rate any public place where I thought some crazy whacked out **** might happen, Wal-Mart would be my #1 selection. I go there every week to grocery shop and I see some of the craziest, whacked out people, and that's just the employee's.
what you call, "better safe then sorry" turns into overreach. it is the same as "shoot first, ask questions later" mindedness. We try to objectively seem like we are doing something for the greater good but end up running things aground like a ship. Reality is, when you assume anything, be prepared to suffer the consequence of what will happen in this case.
