The United States is witnessing frequent shootings, which resulted in hundreds of deaths, such as Saturday's incidents in a Walmart, Texas store (20 killed) and Sunday in Dayton, Ohio (9 killed).

Thousands of Americans held mass demonstrations, specifically during the past two years, to demand that the American administration take the necessary measures to end the chaos of weapons and restrict the sale of automatic weapons; But so far no action has been taken because of the strength of the "lobby" of weapons, while casualties continue.
