Boston police thwart a possible terror plot.

With the help of federal and other local law enforcement authorities, the Boston police stop two men from Iowa, ages 27 and 18, as they try to enter the Pokémon World Championship Tournament at the Hynes Convention Center after concerns were raised about their social media posting. A search of their car turns up a rifle, shotgun, hunting knife, and thousands of rounds of ammunition. The men are arrested the next day at their motel in Saugus.
