I’m not up on the law — so, what charge is brought against a student who mistakenly shoots an innocent student? How about the cop who accidentally shoots an innocent student?
What charges do you bring against a suicided maniac who has just murdered 32 people?
Again, it's a "compared to what?" situation. Even with a few students killed by friendly fire, I bet we'd have seen way less than 33 dead if students had been armed.
Further, after glancing through the thread here, I think incompetence works its way UP the chain. If we tolerate incompetence among the citizenry we will get it from our LEOs. I know I have seen for incredibly incompetent LEO's and extremely professional ones as well. Currently, though, it seems that a lot of us are saying we MUST rely on the incompetent officials rather than strive to make ourselves competent and prepared. That is not the America of the Founders.
