So, one thing criminals do when they finally "gain a conscience" is to either freely & openly admit to crimes they've committed, or they concoct a scheme that allows their being caught.  I believe this Hunter Laptop Episode to be the latter.  Unless he happened to be on a major weeks long crack/meth binge and ignored it as a result.  Either could be the case, but a man like Hunter is easily cracked when pressure is applied like he's been under the past 4 yrs.
