I am aware of that, pdq. I do know that Governors must ask for federal assistance--that the feds can't just march in. When Greyhound's stations (specifically washrooms) had to be 'desegrated' (the old HIS, HERS, OTHER designations had to go), it was not because the Constitution was being violated, but rather because Greyhound crossed State lines, thus making it fall under federal authority.

I would like to know when the Louisiana governor asked for federal help. I will go look.
