It seems to me that everybody is picking up on two things:
1 - the news reports that the victim was specifically targetted because he was OCing. Whether or not the targetting was in order to obtain the victim's gun or not is even more murky that the source of the claim that the victim was targeted because of OC.
2 - the victim has stated that he "usually" CCs and that the only reason he was OCing was because he was in a rush and did not want to go back to his car to get his cover garment. Like most people who attach magical importance/power to certain rituals, he says he now will never change his lucky underpants/forget to wear a cover garment. His "logic" for this is that he was never attacked when he CC'd, he was attacked when he OC'd. Must be the OCing that brought on the attack.
Apparently AlienGear also supports the lucky underpants theory. If they were truely against OC they would pull 25% of their product line and make some sort of statement warning potential customers of the dangers of OCing.
I am more inclined to ignore this FB post and the company itself. They are not big players in the OC gear arena.
