What did they expect??

An NYPD social media campaign backfired when the police department asked New Yorkers for photos with cops and Twitter erupted with unflattering pictures of officers making arrests, tangling with citizens and in some cases wielding their weapons.

Police Commissioner Bill Bratton on Wednesday disputed the idea that the effort was a failure, saying he welcomed the images, and that sometimes police work isn't pretty.

"Send us your photos, good or bad," he said. "I welcome the extra attention."
