The government has developed the tools to turn this country into a police state overnight. Our freedom and liberty are dependent upon trusting government to exercise these capabilities responsibly and not violating our privacy and rights. When you have out of control agencies like the IRS, DOJ, EPA, etc., we should be very afraid.
The tools are there. When a building is knocked down, the hard work is the laying of the wires and explosives over a period of months. The easy part is pressing the button to activate them. This government has been laying its tools for years.
