"Alleged" Careless Shooting by Nigerian Police

"There was traffic around Alhaji Masha road, close to Adegoke and the Police wanted to clear the road. Instead of them to come down from their van to control the traffic like civilized police men or even blow their siren to alert people to give way. They resulted to firing their guns carelessly! They did not even take care to shoot only in the air, they were careless. Then, one of the stray bullets hit a shop around the area and my brother works in that shop! Thankfully the bullet only hit the wall, but it just could have easily been somebody's head! How can the people placed to protect us be our nightmare?
