This Day in Failure: February 18

2008: Civil War relic dealer Samuel White, 53, is killed in his driveway when the nine-inch, 75-pound naval cannonball he is restoring explodes in his face. The blast sends a chunk of shrapnel through the front porch of a house a quarter-mile from White’s Chester, Virginia home and raises concerns about the dangers presented by munitions that remain buried on old Civil War battlefields.

1998: Two white separatists are arrested in Nevada, accused of plotting a bacterial attack on the New York City subway system.

1970: Five of the Chicago Seven are found guilty of crossing a state line with intent to incite at the 1968 Democratic National Convention.
