Toe, The writes: "Predator drones have now racked up over 10,000 hours of airtime in the U.S., largely for immigration enforcement. Homeland Security reports that drone operations lead to the apprehension of 4,865 undocumented immigrants and 238 drug smugglers in the past six years. Compare that to 327,577 illegal migrants caught at the southwest border in fiscal 2011. The only limits on their surveillance are FAA regulations keeping them away from crowded urban areas, and this is for safety reasons, not privacy. While the drones cannot see through windows, they certainly see a lot of what goes on in the (former) privacy of peoples' yards. The article cites Michael Kostelnik from the Office of Air and Marine for the Border Protection service saying he's never been challenged in Congress about the appropriate use of domestic drones. 'Instead the question is: Why can't we have more of them in my district?'"
