It's made national news so I'm sure you've seen it already.
Suspect dropped Someone off at the airport today and a pilot noticed a "This Bike Is A Pipe Bomb" sticker on it and alerted authorities. Suspect was detained and questioned by FBI and ATF for 2 hours and then released. His bike was kept for further investigation but he should be getting it back tomorrow.
This is the third time this sticker (from the punk band of same name) has made national news, and I'm sure there are countless other incidents. I have this sticker on one of my bikes, as do many other people, but one would assume that IF one were to make a pipe bomb out of a bicycle one would not advertise such explosive. Suicide bombers don't paint their intentions on their coats. That's like the mob warning you that your car is bombed.
In related news, as I was searching hypem.com for songs about bicycles I came across a song by The Catalyst titled "This Bike Is A Gravity Bong."
