Public Schools are just a Baby Sitting Service for lazy Parents when it comes to Life Education... If you let the teachers teach things that are in direct conflict with your families lifestyle, it is your fault, that your kids a screwed up... You allowed them to usurp your God Given job of raising your own children... MY OPINION... YMMV...
The George Floyd Memorial area is now a no go area for cops. Probably any uniform. They have a sign up warning white people. And the shop owners are screaming for protection. Police your own. You asked for... no, demanded it. Good luck.
I think it would be extremely difficult. That is why I suggested it in high school. Teens have the ability to think for them self. Young kids need one on one training, and if the parents are pro guns I am sure they are already being taught at home. I think this is a a great start, and wish all schools offered this.
If you are waiting for your turn to be shot and you have balls of stainless steel yell very loudly and move toward the shooter saying "sheriff's department, drop your weapons, we just want to talk" and if you're real luckily then you hear bang, the very distinct sound of a gun dropping on the hard floor, maybe some gurgling... Hey stranger things have happened, remember the guy who got the German battalion to surrender to his company in ww2?
