It's usually the cops giving Occupy Wall Street protesters a hard time. But in this case, Occupy Wall Street supporter and musician Martin Bisi got an NYPD officer disciplined after he snapped this picture of him sleeping on the subway and emailed it to his superiors.

According to the Post, the cop, Matthew Sobota, was off-duty, but was still disciplined. Bisi, who, judging from his Twitter feed is a regular at Occupy Wall Street's general assemblies and events, tweeted today:
