A 10-year-old in Florida has been hit with charges after allegedly threatening a school shooting via text.

Lee County Sheriff Carmine Marceno defended his decision to post the fifth grader’s mugshot and make him do a “perp walk” on camera, following the threats, for the department’s Facebook page. During a Tuesday interview with Fox & Friends co-host Steve Doocy, Marceno did just that and called for a return to “old school” discipline, claiming that parents are now “afraid to discipline their kids.”
