two officers fired at mansur ball-bey after he pointed a hang g handgun at them. >> reporter: we know officers fired four shots, one of them hitting the 18-year-old in the back. we saw just a few nights ago the fact that people took to the streets with violent protests at one point, setting things on fire. in fact, they set a building on fire. they set a car on fire. everyone wants to know what's going to happen next, especially after bricks and water bottles were thrown toward police officers. there was a gun involved and he was running and pointing it toward the officers and they opened fire. the police chief spoke about that a few days ago. >> police work is difficult. split second decisions are made. officers come to work every day wanting to do the best job they can for their community.
