There have been nearly 100 threats leveled against schools in the wake of the Valentine's Day shooting at a South Florida High School. Many of those who issued the threats are teens and students themselves. Some have claimed they were just, "joking." Law enforcement officials say they take all threats seriously and many student have been arrested for them, some, are facing felony charges. But whether those charges will stick is another matter, and state prosecutors say there's no law on the books that bans threats against schools. The ones that are in place for general threats of violence, are in need of updates. Second Judicial Circuit State Attorney Jack Campbell says it comes down one question: Was the threat implicit, or explicit?
