Drones Outfitted with Explosives Seized in Mexico in ‘Active Terrorism Investigation’

Authorities seized drones outfitted with makeshift explosive devices in central Mexico as part of an active terrorism investigation.

I'm thinking this would have been used against another gang. However, I've just been waiting for the news of drones being an integral part of a terrorist attack. I really wish it wasn't so. I have a feeling  they will get banned for all non governmental use as soon as this sort of thing is done once or twice. Sad. You know something is useful and works when it gets banned.
