An interview with Mark Columbo, a veteran MBTA police officer, on what it's like to have a suspect (in this case, a guy breaking into a car at rush hour in downtown Boston), try to punch his way out of an arrest:

Part 2, in which the tide turns when Columbo applies a "guillotine hold" that began cutting off the flow of blood to the guy's head and he gets some bystanders to help subdue the guy.
