Yakuza

Years ago when he lived in Japan the Complete and Total Loser read about a community upset that a local apartment building had been taken over by yakuza, i.e., organized criminals. During a protest outside the buildings one of the neighbors yelled to the building, "Seek an honorable life!" 
This was twenty-five years ago and the Loser still can't think of a better thing to say to the nefarious ones among us. It includes people who would dig through drug store trashcans in search of medical information, whether they're addicts or identity thieves. 
Seek honorable lives, you.

A sticker on a trashcan warns people to think before they toss.
