PLot Hole....
When JCVD put the grenade in that guys pants, and he disarms it...couldn't he have just tossed away the grenade?
shareI thought the grenade wasn't tossed immediately because the scene was set in a warehouse full of fireworks and other flammable material. Even if the grenade landed in a far corner, it still had the chance of causing a more massive explosion. All in vain since the place blew up anyway.
