If this were ever a bad idea, it was probably the worst idea for arguably the most corrupt police force in America.
What the person running the Twitter account probably failed to realize is that most people’s interactions with the cops fall into a few categories:
1. You are talking to them to get help after you or someone you knew was robbed, beaten, murdered, or sexually assaulted.
2. You are getting arrested.
3. You are getting beaten by the police.
In category 1, you are probably not going to be like, “Oh, let me take a selfie with you fine officers so I can remember this moment,” and the other two categories are not things that the NYPD would like people on social media talking about. Additionally, the people who use Twitter a lot (and who aren’t Sonic the Hedgehog roleplayers) are the type who love fucking with authority figures. In any case, #myNYPD quickly became a trending topic in the United States, largely because people were tweeting and retweeting horrific images of police brutality perpetrated by New York City cops.
