Professional protesters from the left ......
 

Professional protesters are stepping things up. Roads being blocked in Arizona. Police lines being assaulted in New York. This will eventually end badly.

Had to double check the date but yeah, it is the 19th:
Radical Leftists Unleash Anti-Trump Riots Starting On March 19th

.

The mainstream media calls them "peaceful protesters"...they are violent disrupters who need to be taken down and it has to happen quick or it will get out of control. Use tear gas and rubber bullets
