Police have dots at three routes entering Brooklyn, and the truck stop might simply be one of those routes.
Perhaps, but why not dots at all entrances to the town then? If those dots simply indicate entrances to the town, then our theory about convergence from 385 and the truck stop is essentially reduced to one of infinite possibilities, and I don't think LE would limit the dots to those locations if they were still going on infinite possibilities. Which is why I think they chose the truck stop for a reason, and the only reason that it could be is that they view it as a specific point in this case.
