IMHO. It will be because there are going to be a bunch of arrests of corrupt (insert whatever foul language to complete the sentance).
This happen quickly to many corrupt people
Heros to some and this will trigger riots (not unlike the rodney king riots, but worse in certain cities)
I honestly dont think the marines will be needed. Good to keep on standby though.
I’m thinking the Marines are for localities where the local authorities decline to cooperate with Federal law enforcement.
