Well, it certainly seems to me that it is LEOs who are going to go to the Dark Side, long before the military that the author is so worried about. The military does have some orginization and controls that should last for a while as we slide toward SHTF. Law enforcement does not, and they will be using what hardware and training they have for their own purposes as soon as they figure it is in their best interests. This may not be perceived as much of a threat to the author, but it will be what people experience first, and it will hasten the slide.
The lesson of Katrina is that when TSHTF, police will desert their posts and look after themselves and their own families first.
