I agree.
I believe the claims of massive numbers of protesters at Trump's Inauguration are simply more pathetic bluffs by the infantile leftists in this country. My response to this is - "Prove it; show up." - and then - "Have fun in the D.C. drunk tank!"
It's just more of the same like "celebrity" threats to move to Canada.
But, I also agree that security personnel need to be prepared ... 'cuz they need to make sure they have plenty of "cry room" space to put these morons in after they are arrested.
