The U.S. government always looks for more laws, when it comes to solving problems. In the discussion of drones, the Fed has the Federal Aviation Administration, the Department of Homeland Security, and other organizations within the Fed looking at the problem.
Who knows what the cost will be, since the government believes it has an unlimited money source.
The Dutch however are much more frugal. The Dutch National Police have come up with a solution for rogue drones, and you will see how they solved the problem, cheaply and effectively, as this video shows.
