Here is an article on the woman who took down the gunman that opened fire in two churches in Colorado.
There are some out there who want to sell out our right to bear arms. I'm sure media and politicians are already trying to spin this story and the recent shooting in Ohio to promote gun control. If guns were illegal, the gunman would have still obtained fire arms one way or another and this woman security guard, would have been defenseless and more lives would have been lost. Because this woman was able to carry a gun, LIVES WERE SAVED! The same can be said for the shooting just over a year ago here in Utah, when a gunman entered Trolley Square mall and let loose, killing 1/2 dozen people. He was stopped by an off-duty police officer having dinner with his wife.
I was try to come up with some way to tie Linux and open source to the above, but I'll forgo such a lame attempt. Just use Linux, you'll be much happier. :)
