US teen gets prison for making 'terrorist threat'

A teenager convicted of plotting to kill fellow students was sentenced to prison on Thursday in what the prosecution called the first case to apply U.S. anti-terrorism laws to threats of school violence.
Andrew Osantowski, 18, of suburban Detroit, will serve at least 4 1/2 years in prison...
Last month, a Macomb County jury convicted Osantowski of "making a terrorist threat" after he wrote messages on the Internet about the possibility of killing students at his Chippewa Valley High School.
Osantowski was also found guilty of possessing a firearm while committing a felony and using a computer to make a terrorist threat.
