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.
