Marion County authorities arrested three men, who claimed to be Occupy Portland protesters, during a traffic stop after officers found fireworks and marijuana inside.

Inside the car, the deputy also found a number of firecrackers and two commercially made mortars inside glass canning jars, designed to be fired into the area during professional pyrotechnic displays. One was found in the floorboard of the vehicle, and the other was allegedly in Luff's jacket.



...When asked about the explosives, the three men told authorities that they knew the canning jar would explode, causing glass shrapnel to fly and possibly cause injury.
