Picture this (admittedly unlikely, given our corporate media) scenario: you're a journalist investigating a corrupt government scheme. An agent comes to your house and is granted access. Eventually you realise they're an agent and ask them to leave. On their way out, they phone in one of these 'indoor drones'. If you get killed, the media will say you were a terrorist. If you manage to destroy the machine, you'll get done for (terrorist) destruction of government property.
Using drones to control/kill humans is a bad idea. Putting aside the inherently cowardly nature of drone attacks, the seemingly inevitable 'collateral damage' just foments resentment (see Afghanistan, Pakistan etc.). Why can't the PTB see that this goes directly against their stated interests?
It's easy to laugh at conspiracy theories but, given the utter stupidity of the Executive, it's no wonder they crop up.
