From the Document: "Thefts of catalytic converters, a key part of the emission control systems of internal combustion vehicles, are on the rise. The devices, which are installed not only on passenger vehicles but also on buses, motorcycles, and commercial trucks, use valuable metals to reduce pollutants emanating from the engine. Replacing a stolen catalytic converter can cost a passenger vehicle owner up to $3,000. These thefts have generated interest among policymakers in what role the federal government can play in addressing the issue. Some congressional offices are examining how existing federal motor vehicle theft statutes might be amended to address this issue."
