Brent's response is compassionate. However, each one of us is a participant the instant we are aware of a situation, private or public. We are not observers. Citizenship, commonsense and responsibilities require a response according to our abilities. As a fraternity under siege, with widely varying opinions, we know the tragedy will precipitate calls for stronger legislation and, more immediately, better emergency response than the feeble and craven action by university and police. Discussion of pro-con challenges here to the Second Amendment is entirely appropriate under the circumstances. Not to thrash and trash, of course, but as something more positive than hand-wringing i.e. salopian and Lowell.
