Wait a minute there Researchers.  The Florida mass murder terrorists attacks that have happened here were initiated by homegrown American citizens that were ISIS empathizers.  There's no stopping underground ISIS empathizers.  But I do support a methodical vetting process allowing Muslims citizenship.  Don't forget that the Muslim leaders across our nation empathized with Bin Laden and screeched into temple mics, "Death to all Americans!"  The FBI knows who these ISIS empathizers are and should send them packing.
