Reporters asked Dotson (St. Louis City Police chief) whether the officers should have used lethal force in this situation given the tensions in the area over Brown's death.

"Our policy is at the end of the day the officer should be able to go home, so (he should use) the amount of force necessary to overcome resistance. If a person is charging you within 3-4 feet that’s a lethal range,” Dotson said.

"I think officer safety is the number one issue and we can all understand the officers' right to defend themselves. I understand what’s going on in Ferguson, but I think everyone has to understand that right and think of officer safety," Dotson said.

Dotson said the officers would be placed on administrative duty while the department investigates the shooting, as per policy.
