And then my theory on the Taurus. I've mentioned some other logical possibilities before, just trying to rule things out, but this is what I think.
First I think they did think the Taurus could be the bad guy, when they reviewed the cams. But they didn't have much info about it. An older burgundy Taurus or something similar is a pretty vague description, and they didn't have a plate to go by. They were trying to get better views from cams, and possibly from the parties in the "vehicles of interest." Meanwhile though, they had profiles of the bad guy from the FBI. I expect the profiles included that he thought he was smarter than LE. Not even mentioning the Taurus, would reinforce that he'd outsmarted them. They knew he'd be watching the coverage. So by looking clueless, and getting some of the facts wrong, the profilers would be telling them, he'd be smug with delight. Maybe a lot of the things they said were designed to tell him "we don't have a clue!" Such as searching west, when he drove east. Naming other cars, then saying they're not sure about the cars afterall. Why would they do that? Maybe the profile said, that if he thought they were on to him he'd just kill her. And that Jayme's best chance of being alive at the outcome was if he let his guard down and she had the opportunity to escape. Maybe that's why the weird messages in the press conference with the aunts & Molly. They figured he was watching, and maybe Jayme had a chance to watch too. In case she did, telling her, come home. Get away! They were right. If they had come busting down his door, would Jayme have survived? It's been frustrating as heck for us trying to figure stuff out with no information, but what if that no information was carefully calculated not for us, but for the bad guy? JMO
