I'd like to try one of those directional sound guns on them--watch their heads go pop!
There was a movie a long time ago with Michael Ironside about people with mind control ability who could cause people's heads to explode. I think it might have been called something like "Screamers", but I can't remember. Ironside played the bad guy who had tried to drill a hole into his head when he first discovered his powers. That type of ability would come in handy for dealing with people like this.
From Wikipedia
Scanners are people with telepathic and telekinetic abilities. ConSec, a corporation specialising in weaponry and security systems, is attempting to exploit their talents. At the start of the film, ConSec's last scanner is murdered by renegade Darryl Revok (Michael Ironside): in a notorious scene, Revok makes the scanner's head explode.
