Boy, now there's a flash from the past! I haven't seen the media drag out the old "deranged Vietnam veteran" canard in quite some time.
The tarot card, experts say, bears a striking similarity to the ace-of-spades death cards American soldiers sometimes left on the bodies of slain Viet Cong.
Only insofar as they were both cards. I'm not sure what kind of "experts" are saying this, it would seem that if this shooter was trying to project that image, he'd use the Ace of Spades.
During the Vietnam War, some soldiers put death cards in the mouths of the slain enemy; others nailed the cards to the foreheads, and still others dropped them from the air.
Airborne used the "Ace of Spades", I don't know about the snipers. From what I understand, they didn't stick around after the fact, they'd "shoot and scoot" because they were usually deep in enemy territory with only one guy for security backup.
He didn't say "veteran". He said "Vietnam War BUFF"!
