There's been a huge debate within the newspaper world -- and beyond -- about a fiery DVD targeting Islamic extremism called "Obsession" that over the last couple of weeks has been packaged in newspaper ads and distributed to hundreds of thousands of readers, especially in swing states.

"I would stay outside for a minute, then go back in, there were a lot of kids," Njie said. "My throat is still itchy, I need to get some milk." Njie was one of several affected when a suspected chemical irritant was sprayed into the mosque at 26 Josie St., bringing Dayton police, fire and hazardous material personnel to the building at 9:48 p.m. Someone "sprayed an irritant into the mosque," Dayton fire District Chief Vince Wiley said, noting that fire investigators believe it was a hand-held spray can.

Many in Dayton are wondering if the mass distribution of "Obsession" has anything to do with this. It's unclear whether or not this was in the works before or after the attack on the mosque, but religious leaders were meeting in Dayton yesterday to talk about the DVD:
