Why I shot Michael Brown Tensions have flared in Ferguson after an officer was cleared of the fatal shooting of Michael Brown. THE officer who fatally gunned down Michael Brown in Ferguson, Missouri described to the grand jury how the unarmed teen overpowered and taunted him. "I drew my gun," Officer Darren Wilson recalled. "I said, "Get back or I'm going to shoot you." He immediately grabs my gun and says, "You are too much of a pu**y to shoot me." " The officer said he was sitting in his patrol car when he drew his firearm after Brown slugged him twice in the face through an open window. They proceeded to struggle over the weapon and Wilson - who is 6 feet 4 - said he was overmatched.

"At that point, I thought I was getting shot," Wilson said. I distinctly remember envisioning a bullet going into my leg. I thought that was the next step. Two shots were fired from inside the vehicle following the struggle, and Brown ran off. After radioing for help, Wilson took off after Brown and his accomplice. "My main goal was to keep eyes on him and keep him contained until I had people coming there," Wilson testified. But then Brown charged at him and the officer fired repeatedly, he said - describing how he fired the fatal shot to Brown's head as Brown continued to charge him. "I saw the last one go into him," Wilson said. It went into him, the demeanour on his face went blank, the aggression was gone.
