The executive director of the Bill and Hillary Clinton Airport in Little Rock, Arkansas, was shot Tuesday as federal agents arrived at his home to serve a search warrant, police said.
"Neighbors also told KARK that on Tuesday evening they saw guns and ammunition being loaded onto a trailer, while firefighters carried a circular saw, crowbars and other tools into the house."
Considering it was the ATF he probably was manufacturing or illegally possessing NFA regulated items. (Machine guns, Short Barreled Rifles, Short Barreled Shotguns, or suppressors)
