However, anger was still evident when Carmichael addressed a rally at Howard warning of, and threatening violence on Friday morning and after the close of the rally, crowds walking down 7th Street NW came into violent confrontations with police, as well as in the H Street NE corridor.
By midday, numerous buildings were on fire, with firefighters attacked with bottles and rocks and unable to respond to them.
Crowds of as many as 20,000 overwhelmed the District's 3,100-member police force, and President Lyndon B. Johnson dispatched some 13,600 federal troops, including 1,750 federalized D.C. National Guard troops to assist them.
Marines mounted machine guns on the steps of the Capitol and Army troops from the 3rd Infantry guarded the White House.
At one point, on April 5th, rioting reached within two blocks of the White House before rioters retreated.
The occupation of Washington was the largest of any American city since the Civil War. Mayor Washington imposed a curfew and banned the sale of alcohol and guns in the city.
By the time the city was considered pacified on Sunday, April 8, twelve had been killed (mostly in burning homes), 1,097 injured, and over 6,100 arrested. Additionally, some 1,200 buildings had been burned, including over 900 stores. Damages reached $27 million. This can be estimated to be equivalent to over $156 million today.

Now that did not work out so well, but I can pretty much guarantee that anything but a protest committed to nonviolence and noninterference with critical services (Police, fire EMS), will be met with force, and will not help any cause it embraces, but will be smeared in the media (remember the SOCIALIST media?) and used against what you are trying to accomplish.
Merely the presence of millions of people will tie up parking, block sidewalks, crosswalks, and increase the lines from the toilets to the restaurants.
That alone will have some effect. Carry signs, wear t-shirts telling them who you are, why you are there, but keep it peaceful.

Block the street for five minutes at a time. The LEO’s won’t have time to respond.
