Under Texas law, threatening a school is a felony offense, even if it isn’t acted upon. According to a release from the Texas Department of Public Safety, students who make threats to a school can be arrested, have a permanent criminal record, face heavy fines, and possibly go to jail.

Nexstar stations across Texas have reported threats to at least 20 schools just this month. On Tuesday, four Bastrop Middle School students were arrested after a threat toward the school was posted on social media.
