If he took his CAC card with him when he went AWOL then hed still have it.
True, but I just thought he might come up on a list, making his using his CAC a dangerous move. The idea they might have known he was in the area is intriguing. Though it's probably more likely he triggered some suspicion.
For active or retired military they don’t usually check a list or run them through a computer. So unless the cop knew the guys name there was little chance he would be caught.
Regardless it seems the lost theory isn’t accurate and this guy might have been planning something bad.
