I see what you're driving at but those arent the same thing at all. Students can choose to engage in either or both. Most people don't choose to be the victim of a school shooting. An armed person walking into a school is like a person going to target practice. But how would target practice be different if the targets shot back? If a shooter had to contend with someone shooting back at them that would have to be a priority over shooting kids, teachers and administrators.
Btw I think handing out condoms in schools certainly is encouraging teenage sex.
Mass shootings are not only happening in schools.
There are 660,693 restaurants in America. Everyone a potential target!
There are 69,485 Bars and Night Clubs in America!
There are 150,154 Convenient Stores in America!
There are 63,348 Supermarkets
115,576 K-12 schools and you can imagine how many classrooms.
380,000 Churches- all targets
How many post offices and government buildings, how many floors, how many offices?
Places of employment are also targets- How many buildings, offices, and warehouses?
Retail stores are a popular target for Mass shootings- can you even imagine how many of them exist!
I'm sorry, but even if you tried to find that many people that want to be guards for these targets of mass shootings, you would never be able to find enough of them.
We cannot even supply all of the jobs needed now with employees!
So I think you are asking for something that is impossible!
BUT I'M SURE THE NRA WOULD HIRE YOU IN THEIR PROMOTIONS DEPARTMENT!
