ST. LOUIS COUNTY - Since the Mike Brown shooting 11 days ago, there have been a lot questions about police protocols and the use of deadly force.
Under federal standards, police officers can use deadly force when they believe that a suspect poses a threat of serious physical harm to the officer or to others.
NewsChannel 5 talked with St. Louis County Police about their training.
"We are trained, we have to qualify four times a year with a firearm. We aren't taught to shoot to wound. You are taught to shoot until the threat is stopped," said Officer Brian Schellman.
Schellman says in St. Louis County, training protocol is always being adjusted and re-evaluated.
