NEW YORK - The NYPD has been overwhelmed by negative responses after a photo request backfired on Twitter. 

The department tried to start a positive social media trend by asking users to share pictures of themselves posing with police officers using #MyNYPD to promote friendly community interaction.  

However, Twitter users quickly turned the hashtag into a stream of photographs portraying police in a poor light and involved in alleged brutality. Pictures include cops clashing with Occupy Wall Street protesters and a woman's hair being pulled by an officer. 

Commissioner Bill Bratton says the adverse reaction was part of the social phenomenon, and wasn't going to change the department's efforts to be active on social media. An NYPD spokesperson also said that the uncensored and open dialogue was good for the city. 

Some people did send in police-friendly photos, which may be featured on the NYPD's Facebook page.
