I wonder how much of this may stem from our own increasingly-digital society. Paper doesn't quite have the same weight (in terms of value/content) that it used to have. I could be way off base, but I wonder how many of those younger guys (and gals) who ignore paper would do the same with a flash drive or laptop?

With reference to digital intel...sure, it's possible to recover data from torched drives, but it's nowhere as easy as CSI-type shows (or IT propaganda) make it appear. There may be the learned assumption that if it's digital it's always going to be recoverable thus there's not the same need to watch over it.

Just two admittedly random thoughts...YMMV.
