What cannon blast?

The cannon shot that ripped into Brett Karch's leg, causing a gaping combat-style wound, has also torn a hole in his hometown community of Snohomish.

Karch, whose leg was nearly amputated and who faces more than a year of physical rehabilitation with an uncertain outcome, has been the target of physical threats because of fears his injury will jeopardize the community's tradition of firing the ceremonial cannon before each high school football game and after touchdowns.
