The state of Florida has been particularly sensitive about school shootings since last year's massacre at  Marjory Stoneman Douglas High School in Parkland.

Now a rapper, Christopher Maurice McCallum, has been arrested for violating a Florida statute that was written in the wake of the tragedy.

The new law states that it is a felony to write or compose something that indicates the person will conduct a mass shooting or act of terrorism. 

McCallum, who was feuding with Yungeen Ace, posted lyrics to Facebook which suggested that he was going to shoot up a concert Ace was playing at the University of Florida.

“Catch you at a Gator game and shoot the whole campus up,” he rapped.

Sheriff Lt. Brett Rhodenizer defended the arrested  

"I haven't listened to the entire song. My understanding is it was very specific as to locations — and concurrent with an upcoming concert," said Rhodenizer. "When the court process continues ... and if ultimately this is not a level of proof where he is proven guilty beyond a reasonable doubt, that's the way the system is supposed to work. But is it probable cause to make an arrest in the interest of public safety? I think so."

McCallum's bond is set at 50K.
