After a school shut-down in Princeton, Minnesota last week, and a recent gun scare at a Janesville school, educators and public safety authorities are worried school pranks are going too far.News 12s Lisa Cownie shows us these antics aren't fun-n-games...Toy guns that look like the real deal in Janesville...recent homemade bombs found at a Princeton, MN high school...Kids that say they meant no harmDavidUlmen says, "We can't afford to take the chance that something like that is a hoax of some kind. It creates a real danger to the one involved, they may be trying to have fun n games, but if we respond and think it's a real firearm, there's the potential of someone getting really hurt."Lisa Cownie says, "Authorities believe neither of the recent Minnesota incidents were malicious in nature, still, those students face charges for a prank gone awry. Parents and students need to understand, authorities have seconds to make judgement calls...anything that can be portrayed as a weapon needs to be left at home."David Ulmen says, "If kids would just think a little bit, there's a place to have fun, you can take your airsoft gun and other replicas and go have fun, but school is not the place to take anything like that."Here are the guidelines provided by the Mankato Area Public Schools.The guidelines include anything that can be used to cause bodily harm, including all types of guns toy or real...loaded or unloaded, also knives, nunchucks...even poisons.Mankato schools did recently implement a threat assessment program to avoid these types of incidents."What we'd like to do is address some of these children before it escalates to the point where they are feeling like they have to bring a weapon to school in order to make their point."Blue Earth Prosecuting Attorney's office says there are legal consequences as well... juveniles need to understand that carrying a weapon, even a replica on school grounds, is considered a terroristic threat, and could bring felony charges.Lisa Cownie, News 12
