From Alex McIlveen, a taxi driver in Glasgow who took down one of the terrorists who tried to blow up an airline terminal. Betsy Newmark has the whole story and more you should read, but I do feel I must cite his effective style of citizen interdiction:
“I ran for the guy and punched him twice in the face with pretty good right hooks. Then I kicked him with full force right in the balls …”
Good on ya, mate.
