I am a teacher. I also have a master's in education. I have published works on education in multple forms.

It took me only a few seconds to find that the dangers of arming teachers.

It is in my professional opinion that if we are to arm teachers it woudl be more cost effective to elimate teachers and implement a hybrid learning system and have the kids stay HOME> It is not worth their lives. Virtually they are safe from anything. Keep em home.

Finally the best solution to this education problem is start with a computer in every students hands. also free wifi for every student.

Now that sounds like a country that is GReAT to me. :)
