2005: That’s the year Volkswagen began a deception that allowed its diesel engines to fraudulently pass U.S. emissions tests. The cheating, it seems, started when VW first pushed diesel engine sales in the United States 10 years ago, and realized its products wouldn’t meet U.S. standards. The company’s chief executive blamed “a chain of errors.” But this was no mistake. Fraud was committed. So, firing employees and paying fines aren’t enough. It’s time for those responsible — all the way to the top — to be prosecuted.
