In regard to Mr. Hite's children not being able to have fun in school: I assume his children are 15 to 17 years old. Playing with a toy gun off-campus might be a joke to him, but his sons need to get over their silliness.
A passing police officer might have had his "playing" son proned out on the ground at gunpoint had he driven by and seen his son playing with a "toy" gun off-campus. Or would he rather it be assumed that it was a toy and have the police officer just drive by?
Schools are faced with tremendous liabilities these days. Somebody at the school cared enough when they heard his son's comment about the "blood" flowing enough to say something.
Mr. Hite would probably be the first in line to sue if this comment were made by somebody else's son and something bad happened to his son as a result.
