Here's an excerpt from that link and yes, this is Islamic law.
A lecturer on Islam affirmed that the victim of rape must produce four witnesses in order to prove her accusation against the rapist.
Four witnesses to a rape. Just think about it. You have a young American daughter and so do I. "Kill him" is right.
Behead him in a public area.. I think on the causeway or maybe even on the meridian of I-75.
Muslims often gang rape women, but I'd doubt that they'd testify against one another.
You are correct, child rapists, regardless of religion, need to die.
