Police vs. Military
Having been a police chief in two different communities, perhaps I see it differently. Once you actually have the job, the principles that effect your actions take on a completely different meaning.
Having the military constantly involved in everyday life is exactly what the founders of our country intended to prevent when they set up the posse commitatus, Second Ammendment and separation of powers doctrines. England was, prior to the Revolution, not only patroling the streets with the military, but forcing people to house and feed them.
Historically, the presence of military in the daily affairs of a country leads to confrontations, abuse of power, unrest, and so on. In the 20's Woodrow Wilson's administration jailed over 50,000 people using federal government agents. They were arrested for things as simple as criticising the government's involvement in daily life.
In 2000 I attended a seminar on traffic control and environmental impact with relationship to all areas of federal, state, and local government control and funding of highways. At issue was allocation of federal funding of local projects. One woman spoke on the topic of air quality and the use of some federally subsidized roads. In that discussion, there were plans presented to place checkpoints that would require someone to justify his use of the roadway or pay an increased toll. That would be done by either entering the reason for your trip by computer ahead of time or being "certified" as a user of the roadway. Persons who did not have the electronic device in their cars would have to stop and be charged a toll based on the type of use. A trip to the hospital or a business use would be less than a trip to the beach and so forth. Please don't tell me that our government too good or too pure to consider managing your daily life with a ID checkpoint.
Be very careful what you ask for when it comes to having the federal government be involved in any part of your life. We live in interesting times.
