The federal government is telling emergency managers to be on the lookout for fake emergency and commercial vehicles during this year's political conventions. The Federal Emergency Management Agency says terrorists could use these "cloned vehicles" to conduct surveillance or carry out an attack.
Security has tightened as officials get ready for the Republican National Convention in St. Paul and the Democratic National Convention in Denver.
According to the National Insurance Crime Bureau, cloning a vehicle is easy and relatively cheap.
For about $2,000 someone can use a computer, color printer, typewriter, barcode label printer, an electric tool for cutting and an engraving pen to fake vehicle identification numbers, stickers and titles.
