An FBI informant secretly records a Muslim extremist making brazen threats to "take up arms" and, if need be, travel to Albany, approach the Joint Terrorism Task Force building and "reach it with a (expletive)-ing Molotov launcher."

Imagine that federal prosecutors ask a federal judge to keep the Muslim extremist jailed until his sentencing for possessing a gun as a convicted felon.
