Ok. So, this guy walks into a bar carrying a bloody chainsaw...

You just cannot make up stuff like this. From MSNBC.com:

On April 25, Gregory Despres arrived at the U.S.-Canadian border crossing at Calais, Maine, carrying a homemade sword, a hatchet, a knife, brass knuckles and a chain saw stained with what appeared to be blood. U.S. customs agents confiscated the weapons and fingerprinted Despres.

If you saw this in a movie, you'd call it stupid and unbelievable.

Then they let him into the United States.

That dear friends, is what is known as a punchline. And, yes, the joke is on us.

The following day, a gruesome scene was discovered in Despres’ hometown of Minto, New Brunswick: The decapitated body of a 74-year-old country musician named Frederick Fulton was found on his kitchen floor. The man’s head was in a pillow case under a kitchen table. His common-law wife was discovered stabbed to death in a bedroom.

Look at the guy's mugshot! He's straight out of central casting.

Sid? Yeah, Sid, it's Larry. Have I got a kid for you! Sure, he can play homicidal manic. He was born to play homicidal maniac!

But seriously, folks, these are our borders we're talking about. We cannot survive as a nation if these circumstances continue.
