If you research about the incident, then you will find out that it had hardly anything to do with the Bitcoins. Ali Shukri Amin was sentenced to 11-years in prison, for recruiting American citizens to fight for the ISIS. He had already helped one of his recruits (the 18-year old ethnic Iranian Reza Niknejad) to travel to Syria. Amin was caught before he could send more recruits to the ISIS territory.
