I’m curious, if the FBI was tracking them, why did they not arrest them when they crossed the border into the U.S. or long before they got close to VA?
And I ask this due to the fact there is always a chance or risk they lose the suspects while tracking them.
I can only assume it was because locking some Canadian up for immigration law violations isn’t something that’s very sexy. So track him, see who he talks to, see what they plan. And unless he’s about to blow up a church, gather more evidence. Guess between transporting a full-auto rifle and the proximity to the rally, they decided to grab them.
