re: So was it an OBer that pulled a gun at Walmart today

I wasn't there but was told by someone who should know that another shopper saw the incident and was trying to run away and ran into a display/fixture causing it to fall over and make a loud noise. He also cut his arm on the display/fixture resulting in people seeing blood. This mixed with someone with a gun and loud noise caused people to believe he was shot.

Might be BS but sounds plausible.
