“What was supposed to be a celebratory lesson in American history has sent three children to the hospital,” cnn.com reports. “They were a part of a Civil War re-enactment group watching a parade in Orem, Utah, when a cannon set off an explosion Saturday. Witnesses said two of the three children injured were initially engulfed in flames, according to CNN affiliate KUTV.” Well that sucks. But what the hell are civil war re-enactors doing giving a cannon access to explosives? Let’s try that again . . . “The cannon was fired, and a spark landed on a pouch containing additional charges for the cannon. The smoldering ember set off the contents of the pouch, blowing it up and injuring all three children, the [Orem, Utah Department of Public Safety] press release explained.” Cue calls for cannon registration in three, two, one . . .
