Wisconsin High School student invents classroom door stop

From Gateway Pundit:

A Wisconsin high school senior and Army recruit Justin Rivard invented a door stop that prevents killers from entering classrooms.
Justin created the “JustinKase” two years ago when he was just 15. The device does not allow a door to open even a crack which means students and staff will be saved during emergencies.

His own school already ordered 50 of the “JustinKase,” one for each room in the building, according to KARE.

Justin is entering the Army this year after his graduation.

    Can I have Justin come and defend my son’s school? Please?


  2. It is a great invention and I hate to be skeptical, the kid is pretty bright, but what would stop someone from shooting the window out, stick their gun through the broken glass and start firing? Of course they could always use Lexan instead of glass I suppose.

    What a great idea! Congratulations, Justin.

    My wife, a retired public high school teacher (44 years on the job) loves this device, but adds a note of caution: Someone inside the classroom who wants to assault other students, or perhaps assault a teacher, can use the device to make it impossible for rescuers to come to the aid of the person or persons being assaulted. Let’s call that a one percentg problem, but also recognize that is is a potential problem.

    Whatever happened to industrial arts classes? To trade and vocational education? You know, those people that keep you cool in the summer and warm in the winter? The people that maintain your car? Build homes, fix your toilet? Pour concrete, fix potholes, repair computers, wire your home for electricity? Fix your appliances? Tool and die technicians? Machinists, mechanics and CNC operators?

    I can’t speak for the US, but at my former high school (and other high schools I’m told from my mom when she goes in to sub teach at them) it has become a joke. Home Economics used to teach real life skills to learn how to run and manage a household. Now they teach things like how to make fruit salad out of expensive exotic fruits (something that causes my mom to give the home ec teacher a long lecture on about teaching completely useless skills and not equipping students for the real world) and how to bake cookies (something I learned and was doing when I was 8). My high school still has Industrial Arts, but it’s not why it used to be because they don’t have skilled teachers to teach it. Obviously one needs more than A teaching degree And teaching certificate to teach work working and welding.

    We didn’t have anything automotive, but when my brother left high school he could weld with enough skill to work as a non-journeyman welder and get a decent paying job temporarily before Finishing his post graduate studies and start his career.

    Pretty nice invention. Good job, Justin.

    Of course, it does have limitations. First, it depends on making base plates that match with the specific door jamb and wall location, so it cannot be mass-produced. But that’s OK, not everything needs to be mass produced. More importantly, when Justin says the intruder “can’t” get around it, I sure hope he has a lawyer writing the cautions and limitations. Because (just as an example) the welds can break. Door hinges can also be shot out – the device assumes the hinges are holding one edge of the door. There may be other ways it can fail (such as being installed incorrectly by a moron who doesn’t set it in place properly).

    Very clever idea.

    The public school where we have our religious ed classes has something a little simpler on the door jambs; a metal plate; I not sure how it works.

    I would also like to see a product where the school video surveillance is broadcast on WiFi (in real time, not a 20-minute delay) so that first responders could see inside the school from a place of refuge outside the school.

    Home Econ has been cut from our local high school and Industrial Arts is only offered in 9th grade for one 9 week quarter. These cuts were excused due to required testing from the fed and the fact that they can’t get students to pass the requirements, so “optional” studies are to go.
    It is sad, because we learned how to cook, financial planning, how to rudimentarily sew and meal planning as well as other tangible life skills in home economics, and a lot of us overcame our fears of tools and learned proper use of them in “shop” as it was called.
    These are things we teach at home, however, sadly most kids in the world today are not taught these things and they are actually needed more than ever. A lot of people have no idea how to cook or operate a hammer even.
