Is there not a rapid response call out for the police helicopter on infringers?
That would cost money!!! Don't come with the "A mid-air would cost a lot more money" because the money for the mid-air would be from the carrier's insurer and the money to inspect and deal with the intruder would come from Police and/or ATC and they will not be willing to pay that up front. Even if they then had powers to sue the intruder for the cost.
So, what is needed is the equivalent of the commercial companies that carry out car clamping. They would get a percentage of each intruder that they track, identify and prosecute.
