A lot of the anti-drone thing in the UK is a linking of 'our' drones which (I understand) operate effectively in the CAS role in much the same way as a manned ac does, with the CIA/Obama-approved targeted assassinations which currently happen in various countries around the Middle East. The legality/morality of this is dubious at best and undoubtedly causes collateral damage (death of bystanders).
Perhaps MoD
PR needs to be more aggressive in its explanation of this particular weapons system.
