Analyst's note:  Absolutely must read.  If you have a hammer (drone), everything looks like a nail (farmers & private property). What else is the federal gov't doing with the aerial drones that we don't yet know about  ... over our nation? Don't overlook this article as well The Age Of Drones: Military May Be Using Drones In US To Help Police.

Obama’s Environmental Protection Agency is using aerial drones to spy on farmers in Nebraska and Iowa. The surveillance came under scrutiny last week when Nebraska’s congressional delegation sent a joint letter to EPA Administrator Lisa Jackson.

[....] In fact, the EPA has absolutely zero authority and is an unconstitutional entity of an ever-expanding and rogue federal government. Article 1, Section 8 of the Constitution does not authorize Congress to legislate in the area of the environment. Under the Tenth Amendment, this authority is granted to the states and their legislatures, not the federal government.

The EPA has not addressed the constitutional question, including its wanton violation of probable cause under the Fourth Amendment. It merely states that it has authority to surveil the private property of farmers and ranchers. It defends its encroaching behavior as “cost-efficient.”
