Wingnut Nebraska cattle ranchers upset over EPA flyovers

If I'm understanding this new outrage from Nebraska, government drones looking for illegal immigrants is just honky dory and makes sense but when the EPA flies over cattle ranches to photograph, that's an invasion of privacy. Suddenly the "if you have nothing to hide, why should you care?" mentality is out the window when it's them. I see.
Have I missed something here or are the repugican politicians and cattle ranchers hypocrites?

A Nebraska cattlemen’s group is pushing the Environmental Protection Agency to stop pollution-control flights over ranches, claiming it amounts to spying on citizens. EPA, meanwhile, says the flights are an effective way to quickly spot -- and stop -- pollution from manure lagoons and other waste at large livestock operations.

Nebraska's five federal lawmakers joined the fight this week, demanding to know on what authority EPA is flying over and photographing private property. The lawmakers sent their demands to EPA chief Lisa Jackson on Tuesday, listing a battery of questions and demanding answers by June 10.

EPA has been operating these flights across the country for nearly 10 years.

When the repugicans owned Washington, aggressive invasions of privacy (including obviously the EPA flights) somehow made sense and were for freedom and protection. Why was it OK then or for other issues? Both parties will easily abuse any rights given to them as we are about to see with drones flying over the country.

In the case of EPA flyovers, it's difficult to imagine how much more the flights can provide compared to satellite images that have been possible for decades.
