Burn Notice2007

Michael Westen:
[narration] When you booby trap someone else's place, you put the trigger in the door or just inside so the odds of tripping it are much higher. If you rig your own place, the trigger has to be farther inside so you can safely enter. A trip wire is a quick and dirty version, but a contact plate under the rug is completely undetectable. Put a little accelerant on the walls... there's a reason they call it a firetrap.
