I don't quite understand what the SAM's are for... However in other news did people see that terrorist in the USA that was making long range RC-planes with jets able to do 600mph? Basically an UAV, except he strapped C4 to it and planned to fly it into a building.
Also anyone on here go on TED? There's a recent video about future crimes on there, good food for thought as he goes on about how laws on firearms are very strict in the UK, but with the uprise in 3d printers you could just print a gun off. Some of the idea's of what the future may hold is a bit scary.
