I agree, sounds like a ploy - why attempt to whack over a dozen people and [b]then[/b] ask for money?
Its too cloak and dagger like for a fella who can't spell well in his letter to have an "off-shore" bank account. Some poor little old lady is going to get her door kicked in somewhere in Oklahoma because the shooter said "deposit the money is account ummmmm, I dunno, 123456789."
After all, the 'pro-profilers' on the news have been saying "Its most likely not a terrorist, as they havent made any demands" [rolleyes] WTF.
So, the shooter says, I'll make some demands - I want all pandas released from all US zoos. Next thing ya know, Jeff Corwin from Animal Planet will be standing besides Chief Moose at the next press conference - saying "we followin' all da leads"
Watch the LE dance.
