U.S. troops firing on citizens? Not that far fetched.
“THE SAD TALE OF THE
BONUS MARCHERS”
http://www.worldwar1.com/dbc/bonusm.htm
These were veterans our troops attacked. Back then, the troops that attacked the Bonus marchers were probably so conservative they would make FReepers look like liberals, but they attacked WWI vets without hesitation when ordered to do so. What makes anyone here so confidant that our military today would hesitate to attack citizens if ordered to do so.
