Well land mines don't kill everything, look what happened in the Falklands; http://www.mentalfloss.com/article/25973/how-island-full-landmines-led-thriving-penguin-populationFappy said:I was thinking the same thing. Kind of like when an antique gun backfires DXMikeWehner said:Probably more than anyone of us would feel comfortable with. It's kind of like the landmine problem; weapons of war don't surrender once one side wins, they just sit and wait to to kill something.Fappy said:It makes you wonder how many other old war relics are lying around out in the world ready to blow.

In this case, I doubt the cannon would have been able to successfully fire the ball, given its deteriorated condition. I imagine if the black powder had been ignited, the cannon itself might have just turned into a giant bomb, which could be even more deadly.
