Public demonstrations, especially those that are large-scale like March For Our Lives, require a permit from the police department of the city in which the demonstration will take place.
European political researcher Ole Dammegard contacted the Metropolitan D. C. Police Department concerning the permit for the March For Our Lives demonstration in Washington, D.C.
Dammegard received this email from Officer Scott C. Earhardt of the Homeland Security Bureau of the Metropolitan Police Department:

Some Facts:
The shooting at Marjory Stoneman Douglas (MSD) High School occurred on February 14, 2018.
A day after the shooting, on February 15, 2018, MSD students formed the group, Never Again MSD.
On March 24, 2018, March For Our Lives demonstrations took place in Washington, D.C. (and other cities).
Among the organizers of March For Our Lives is Never Again MSD, which had not existed before February 15.
The D.C. Metropolitan Police Department received a permit application for March For Our Lives demonstration “several months prior to the actual event”.
Questions:
How can Never Again MSD apply for a permit “several months” BEFORE the group had even been formed?
How can an application be made for a permit for a “March For Our Lives” demonstration “several months” BEFORE the Parkland MSD school shooting that galvanized MSD students to form the Never Again MSD group that organized the demonstration?
