My friend found a landmine 6 years ago, in the UK, but luckily it was defunct.
For those who carry a fire arm, how many times has carrying it saved your life?
Thought you deserved an answer.
Last December there was a shooting in a shopping mall in the western US, a state called Oregon. A disturbed person with a rifle started shooting randomly, killing two and wounding another when the rifle jammed. This next part didn't get much coverage in the news media:
While trying to clear the jam of his rifle, the disturbed shooter was confronted by a fellow who happened to be (legally) armed with a handgun. Not a cop, not a soldier, just some guy who drew his weapon and took aim at the shooter but didn't shoot because there were innocent people behind the shooter who might be injured. The shooter saw this fellow aiming at him and ran off, found a secluded place to hide, fixed his rifle and shot himself.
Nobody knows how many lives were saved because of all of this; it could be many, it could be none - we will never know.
Here's a link to one of the few media reports about it:
