Here are the change in policies I would recommend for Schools and Home
1. Institute school prayer every day.
2. Create posters that are based on scripture, you could have at least 10-20 different ones posted in any school, both in the classrooms and in the hallways.
3. Encourage a bible study club at any school. (The way clubs work is that teachers will list what club they would like to run and then if they get enough kids interested the school will fund the club. However, a teacher cannot do a Bible study club, only kids can organize it and then the kid has to find a teacher who will host the club. This makes it very difficult because teachers are not permitted to talk about their Christian faith at school so how would a kid know which teacher to ask?)
4. Rather than referring ADHD and other types of disruptive kids to big pharma, refer them to someone who will focus on their diet and exercise. There is a very strong correlation between using psychotropic drugs and school shooters.
5. Instead of paying for a large team of cops to provide security to every school instead fund Music, Art, Drama, and after school sports programs. The high school I was at had about 8 full time cops, the salary for one full time cop would cover 8-10 after school programs.
6. School disciplinary issues should result in calling in the parents and determining if the kid is playing violent video games and watching porn. Then, rather than expulsion the parents hand over the video game and TV. Schools also have parent coordinators who visit homes. So once a kid is identified as a problem kid the parent coordinator will visit the home so this is not simply "the honor system". Let's vilify violent video games and pornographic TV.
7. School disciplinary cases should also be able to mandate a kid attend after school programs.
