Federal officials had heard stories about Scott Vitkovic. People at his Cambridge mosque said he wanted to attack the United States. And he had worn an Osama bin Laden T-shirt, outraging one mosque member who called it “completely irrational behavior.”
That was enough to get Vitkovic, an immigrant from the former Czechoslovakia, locked up in the secretive immigration system for the past seven years without ever being charged with a crime. Vitkovic denied in court records that he was a threat to anyone but himself, saying he had once attempted suicide and had been treated for depression, but federal officials remain determined to deport him as a threat to public safety.
