I've written about this incident before.
The big offense, interestingly, isn't for assaulting the guy. Early reports are that he's just going to get a misdemeanor bang on that. Officer Pogan is going to get fired for creative writing in the felonious degree.
According to the New York Times:
Officer Pogan arrested Mr. Long and charged him with attempted assault, resisting arrest and disorderly conduct. In his police report, Officer Pogan wrote that Mr. Long was obstructing vehicular traffic as he rode southbound on Seventh Avenue. After instructing Mr. Long to stop, Officer Pogan wrote, Mr. Long rammed him with his bicycle, causing the officer to fall to the ground and receive cuts on his forearms. Mr. Long then resisted arrest, Officer Pogan wrote.
Who would have ever thought that there might be somebody with a camera? It's not like it was Times Square.... Oh, wait.
