We make Islam and the Koran illegal in the USA,America was founded on the basis of religious freedom. Sorry, but you have to go after the actual perpetrators of these crimes. Islam can only be defeated through education and enlightenment, and not by using the power of government.
Sorry, but I disagree. Religious freedom DOES NOT extend to any "religion" which demands the dissolution of the US Constitution and openly attacks and murders other citizens.
By it's very nature, Islam has openly declared war on the US government and its non-muslim citizens. The government has every right and duty to extinguish it.
The people have every right and duty to demand that the government extinguish it.
