Less than a day after initiating a policy of putting signs on houses investigated for drugs as a result of a Crimestoppers tip, New Orleans Police Superintendent Ronal Serpas rethought the idea and canceled it.

The placards that were to be placed on houses read, "The NOPD has served a narcotics-related warrant or checked this residence as a result of a Crimestoppers hotline citizen's tip."

Serpas says the placards initiative was put in place when he oversaw the Nashville Police Department, and it worked well there. But critics argued the proposed crime-fighting tool might target innocent people.

On Wednesday, Serpas said he would look for other ways to notify neighborhoods of efforts to get rid of drugs.
