It turned out the store owner was a Sikh from India, and the reason he was shot was because the guy saw the turban and beard he was wearing and thought that was the mark of a terrorist. What made it even sadder was that the dead guy's family was devastated, but they completely forgave the shooter.
His brother was my neighbor. Brother took off the turban and started wearing a baseball cap after that. I don't think the area is sensitized to something like that. It was horrible.
It's too bad, really tragic. The turban that a sikh wears does not in any way resembe arabic headgear...
