Yup....I can't say I would want to see kids get educated in an environment where guns are with every guard at every corner...It seems like it would feel way too "prisony" and wouldn't foster a good setting even though it could potentially provide the necessary safety.
I heard on NPR on my way home from work that there are about 20 or so mass crowd shootings every year in the USA on average and less than 200 people total on average die as a result (I think they said 150 but I was surprised at how low the number was). On the flipside, there are more than 15,000 homicides from non-crowd level shootings.
Basically, although it is a very very shitty situation, when put into perspective it just sucks to come to the realization that it really isn't as big of a deal as it seems......It's tough to write that but it's true if the numbers reported in the previous paragraph are true.
