Platinum and Iridium plugs perform at a lower level than copper spark plugs, because they are less conductive and they tend to overheat. However, the overall longevity of these two types of metal is better than copper plugs. In reality, copper has the best performance of all three and the worst longevity.
If a local restaurant, for example, used a celebrity's name or image in a commercial and implied an official endorsement, it could face an invasion of privacy lawsuit. This type of legal action is often taken against advertisers who morph the faces of celebrities onto other bodies to imply endorsement of a product.
It is important to point out that these concerns about a potential invasion of privacy did not start with the passage of the Homeland Security Act. Over a year ago, critics pointed to the hastily passed U.S.A. Patriot Act which widened the scope of the Foreign Intelligence Surveillance Act and weakened 15 privacy laws.
