litterbugs can run, but they can't hide

Littering was pretty much a faceless crime until the people at Hong Kong CleanUp finally had enough and decided to call litterers out for their dirty deeds. Using a combo of DNA testing, analysis, phenotyping technology, and some other magic, Hong Kong CleanUp and their agency, Ogilvy & Mather, collected litter off the streets to create composite sketches of the litterers' faces and posted them on ads throughout the city. Waiting 30 seconds for the next trash can sounds like a much better option than having your grill appear here, no?
