Tell the DOJ: Hold VW executives accountable

Volkswagen installed "defeat devices" on some 567,000 "clean" diesel cars in the U.S. to avoid emission control laws. These devices are elaborate software that turn on emission controls during testing, and turn them off during regular driving. As a result, these cars can emit as much as 40 times the legal limit of NOx, a major smog-forming pollutant.

The Justice Department has been seen as the only agency that might hold executives personally accountable for this wrongdoing. While they have filed a civil suit to levy penalties against the company, they haven't pressed individual criminal charges yet -- so they need to hear from you.
