just in case you haven't gotten your daily dose of WTF. it's really worth it to go read the article and the one it links back to. we give authorities privileges that aren't afforded to normal citizens so they can "serve and protect" us. but in this case, even if it was an accidental discharge as claimed, you have to wonder what possessed this guy to unholster his weapon around children and point it at one in the first place.
the risk with establishing authorities is that we may be giving power to the wrong people. this appears to be one of those times.
