While watching a recent episode of Corbett Report, I saw an entertaining segment which discussed the use of garbage trucks to monitor the neighborhoods along their routes for "irregularities." These not-quite-normal items of interest could then be held as archived videos which might prove of interest to authorities such as DEA, ATFE, FBI, IRS or local police. The Corbett piece - in conjunction with Media Monarchy - even discussed arming garbage trucks with video-scanning capacity to capture "suspicious" license plates.
While many citizens might well view this sort of thing as a welcome addition to the national surveillance toolkit, others might suppose that this was carrying the "neighbor watch" program beyond reason. However citizens weigh the matter, this proposition need not end at the garbage truck.
It authorities and private enterprise join hands in policing neighborhoods to achieve enhanced security, the garbage truck will not be the end stage of enhanced security.
I can easily envision Got Junk? trucks visiting customers throughout the United States and, while inside a home ostensibly to pick up junk items for removal, scanning for firearms, videotaping same for weapons identification purposes, and perhaps using technology (as in airports) to scan areas of homes for probable weapons. Again, these videos could be archived for future viewing by ATFE or nationalized swat teams on confiscation missions during periods of upheaval and/or martial law (as in N.O. during Hurricane Katrina turmoil). After all, firearms equal "potential enhanced resistance" to the United States wing of the global nation state. For such people the U.S. constitution was - and is - just paper.
Moral of this story: Sophisticated home invaders don't carry signs alerting folks of their intentions.
