A Detroit-area man accused of being a vigorous supporter of the Islamic State group has been sentenced to nearly four years in prison for a weapons crime.
It's a significant break for 30-year-old Sebastian Gregerson. Prosecutors had asked for a five-year sentence Wednesday, repeatedly emphasizing his support for IS, a violent Islamic militant group, in writings and secretly recorded conversations.
But federal Judge Arthur Tarnow says there's no evidence that Gregerson committed any dangerous acts.
The FBI used an undercover operative to get close to Gregerson. He pleaded guilty in March to possessing unregistered destructive devices.
Federal prosecutor Cathleen Corken says the FBI arrested Gregerson before he could commit an act of terrorism. But defense lawyer David Tholen says the government greatly "overstated its case."
