The New York Police Department has discovered the perils of trying to engage with Twitter to boost its own image, after a campaign to get the public sharing pictures of "#myNYPD" prompted thousands to share images of apparent police brutality.
Launching the hashtag last night, the force asked members of the public to tweet them "a photo with a member of the NYPD", adding that it may be used on the department's Facebook page.
Do you have a photo w/ a member of the NYPD? Tweet us & tag it #myNYPD. It may be featured on our Facebook. pic.twitter.com/mE2c3oSmm6
The request actually received a number of positive replies, with people posting images of themselves arm-in-arm with smiling, helpful police officers. To the first of these, the force even responded personally, saying: "Thanks for the photo! Keep them coming..."
Yet just one hour after the initial post the mood changed, and what followed was a torrent of anger and sarcasm about how "helpful" the NYPD can be.
