In Sri Lanka, where terrorists has used suicide bombers and remote control bombs for nearly two decades, the government has banned the importing of radio controlled cars, aircraft and boats. The government fears that terrorists would, say, maneuver a radio controlled truck, loaded with five pounds of explosives, so that it ended up under a military vehicle. Then, boom. No terrorists have tried this, and maybe none have even thought of it yet, but someone in the government believed it better to be on the safe side. The local terrorists are Hindu nationalists, who were the first modern terrorists to use of suicide bombing on a large scale.
