It really bothers me when politicians and political activists use things like this to try to prove a point. This is a multi-use device to protects kids. Its not a bullet-proof vest that can be used in other things. I want to give some examples why this would only be a help against a gunman, but that they can get around it, but as I started typing I felt really uncomfortable with it. I know what you will read into that, but your wrong. It's the knowledge that I have kids and the only way to stop one of these gunman 100% is to drop them. Gun restrictions won't do it. Outlawing guns won't do it. Putting them in the ground will. I don't necessarily agree with arming the teachers, but I would agree with security at all schools. Whether it is private security, or police. Unfortunately, most schools are underfunded as it stands right now. But that is another issue. Let me ask you something else. The government wants to control our lives and in places are getting ridiculous with it (eg no 32 oz pops), but they won't fund schools properly. What exactly are the governments priorities? Oh yeah, giving billions to countries that hate us. Overpaying on public works. Spending millions on grants that shouldn't be paid out (eg what was that solar company that got funded then went bankrupt). Spending all their time arguing on factions ideoligies, rather than doing what they are paid for, which is working together for the public good. Screw the schools though, right?
