"When you encounter the enemy leader, you have to eliminate him--then and there."
...and even if that "there" happens to be a mosque.
Mosque's maybe used to be a place of worship, however, I see more proof all over the world that they are a base of terrorist operations, from brainwashing to hate-education, from recruiting the most militant to actually storing caches of weapons and planning tactical operations, they simply abuse our 'good virtues' against us.
