You're standing near the entry/exit doors at Wal-Mart. Two corn row-haired, gang-bang looking thugs walk in. They've got gang graffiti tattooed all over their anatomies. They each carry an exposed chrome-plated .45.
Your natural reaction is:
A. Get on your cell phone and call the police immediately.
B. Do nothing, because these guys are obviously constitutional scholars just testing the waters of open carry civil rights.
Carried openly in a holster?
Like Big Dog said:
"go about your business and maintain situational awareness"
Life is a constant series of decisions which are based on situational awareness, circumstance, and particulars (among other criteria), coming from an almost infinite pool of options, which can't simply be limited to 2 potential paths.
