At the same time, the ticket-fixing inquiry now underway is hardly the department's only recent scandal. Secret tapes made by an officer in the 81st Precinct revealed numerous instances of lawbreaking and troubling departures from protocol (This American Life did an excellent version of the story in Act Two of this episode). "Precinct bosses threaten street cops if they don't make their quotas of arrests and stop-and-frisks, but also tell them not to take certain robbery reports in order to manipulate crime statistics," The Village Voice reported. "The tapes also refer to command officers calling crime victims directly to intimidate them about their complaints."

Two officers are currently on trial for rape. Last year, an officer was charged with having "lied to cover up several unlawful stops and seizures in Manhattan and forced subordinates to falsify paperwork to justify the stops." Other major scandals - some merely alleged, others proven - are outlined here.

It isn't that NYPD officers are irredeemably corrupt, or that they're unfairly maligned, though there are instances when both of those things are true. The point is that even in one of the most professional, highly scrutinized police departments in the country, serious misconduct happens. Corruption and abuses are inevitable anytime some human beings are vested with so much power over others. In cases involving proven misconduct, an additional troubling feature is that there are often a lot of officers who observed wrongdoing but did nothing to stop it.

Here is an inescapable conclusion: police officers in New York City need to be monitored more closely. So do police officers everywhere else. Were it up to me, the cops of America would have a dashboard camera on every cruiser, a digital audio recorder in every pocket, a camcorder running during every interrogation, and secret internal affairs officers operating in every precinct. The exoneration of wrongfully accused police officers would please me as much as the bad cops who were punished for breaking the law or acting unprofessionally. I'd also pass a federal law permitting United States citizens to record the activity of on duty cops without fear of being prosecuted (nope, you don't necessarily have that right already, depending on where you live). Reason magazine's Radley Balko wrote a great how-to guide on the subject here.

Over the years, law enforcement has used ever more sophisticated surveillance equipment to monitor citizens. As every police scandal reminds us, the ticket-fixing story included, there is good reason for citizens to become far more sophisticated in our monitoring of on duty police, and the law ought to permit our doing so.
