It probably means 1 of of a few things:
1. The brand new koran next to the device is simply ‘coincidental’
2. The guy who found the device and where the koran was found under his truck did this.
3. Someone was specifically out to get this guy.
4. The guy who found the device was not the target but it was planned that way and anyone was a feasible target, and by doing it this way they could get away.
5. Probable connection with that Jordanian guy who wanted to blow up a downtown Dallas skyscraper (Fountain Place).
6. Has to do something with the Detroit Christmas underwear bomber.
Really? I never even seen a copy of it anywhere including a bookstore, let alone just lying in the street. I have never even seen a Bible just lying in the street.
