Q: Did Darren Wilson carry a Taser, and if so, why didn’t he use it against Michael Brown instead of his gun?

—Charles Tatter, Marietta

A: Wilson, the Ferguson, Mo., police officer who fatally shot Brown on Aug. 9, didn't have a Taser, or stun gun, according to his St. Louis County grand jury testimony. "We only have a select amount," he said. "Usually there is one available, but I usually elect not to carry one. It is not the most comfortable thing. They are very large. I don't have a lot of room in the front for it to be positioned." Wilson said he was trained to use a Taser. He also opted not to use Mace, which was on the left side of his belt. "The chances of it being effective were slim to none," Wilson said. "(Brown's) hands were in front of his face. It would have blocked the Mace from hitting him in the face." Wilson testified for four hours.
