The best-laid plans of mice and would-be terrorists:
>The FBI has arrested a man who authorities said thought he was going to carry out a bombing attack on the U.S. Capitol building but was in fact dealing with FBI undercover operatives for the past few months.
The man, said by law enforcement officials to be from Morocco and in his late 20s, was arrested about noon ET Friday near the Capitol after he received what he thought was a vest containing explosives. In fact, it had inert material that wasn’t hazardous.
