ATLANTA (MCT) — Brent Doonan got a sick feeling when he heard a crazed gunman fancying himself as the Joker shot up a Colorado theater last month. It returned again last week when a white supremacist went on a killing spree in a Wisconsin temple.

“The first thought is always the same, you know what the victims are going through,” said Doonan, who was shot five times in 1999 when a smiling gunman named Mark Barton rampaged through two stock trading offices in Atlanta, killing nine people and wounding 13 more.
