The nonprofit Security Grant Program provides Jewish schools with far more $$ for security enhancements than they do for other religious schools. Separate states also have security funding for schools. Investigate, see if the schools in your town have received any of these funds and how the funding was allocated after it reached the local level.
The photos I saw of the Parklands school sadly make it look like a quasi military fortress but that may be the reality of today’s world if it keeps our schools safe. I know the yeshivos and day schools in our area have tapped this federal program for funds but the demand way exceeded available funds. Ultimately , each yeshiva must do its own threat assessment relative to its physical facilities and do whatever they can afford, federal funds or not.
The Parkland shooter was a very disturbed kid with a long history of problems and “red flags” that were ignored. The authorities had many opportunites to take preventative action but failed to do so.
If there’s a dangerous bull in your village, you don’t turn the village into a fortress. You confine the bull so that he can’t hurt anyone.
Last March FL gave $2M to private Jewish schools for security, NY state received $25 million this past June, some of the funds were allocated to Hebrew Academy of the Five Towns and Rockaway (HAFTR) and Magen David Yeshivah, just to name a few. (Do a bit of googling to find the entire list of the awardees and amounts, then ask your school what has become of the $$.)
