And last month, there were two horrific shootings, the first in an elementary school in Texas that killed 19 children and two teachers, and the second in a supermarket in New York that killed ten people, all of them black. As a result, calls were issued to organize protests scheduled for Saturday in hundreds of places.

But the problem of armed violence, which has killed more than 19,300 people so far in the United States this year, according to the Armed Violence Archive, exceeds the mass murders that receive great attention and follow-up, and the majority of deaths are caused by suicide. 

"After countless mass shootings and armed violence in our communities, it is time to get back on the streets," the protest organizer, March for Our Lives, declared on its website.

She stressed that the move aims to "understand to our elected officials that we demand and deserve a nation free of armed violence."
