Pet Peeve

Main Entry: martial law
Function: noun
Date: 1933
1 : the law applied in occupied territory by the military authority of the occupying power
2 : the law administered by military forces that is invoked by a government in an emergency when the civilian law enforcement agencies are unable to maintain public order and safety

Note the spelling.
It is not “marhsall law” unless there’s some guy named Marshall who’s running around enforcing the law.
If you’re going to get all paranoid and start blathering about how the UN, New World Order, and Black Helicopters are going to be cavorting around Anytown, USA in some attempt to take away our rights, at least learn how to spell “martial” correctly.
You might still be a crazy nutjob, but at least you won’t look like a total idiot.
