Cambridge debates switching on its surveillance cameras after Marathon attacks

The city of Cambridge, MA is considering whether to switch on its network of surveillance cameras. Councillor Craig Kelley, who chairs the Public Safety Subcommittee, scheduled three public hearings on the newly proposed Security Camera Policy, but they were poorly attended. The City Council voted unanimously on July 2 to ask the Mayor and the City Manager to arrange a better-publicized meeting to discuss the Policy.

ORDERED:
That Her Honor the Mayor and the City Manager be and hereby is requested to arrange a community meeting with other stakeholders to discuss the proposed Security Camera Policy submitted by the Police Department for implementation.

The minutes of the July meeting are here.

This is the history.


Back in 2009, according to the ACLU of Massachusetts, the City Council voted against installing security cameras, but got pushback from the City Manager, who argued that Cambridge would jeopardize its ability to get future grants from the Department of Homeland Security if it did not actually install the cameras. A compromise was brokered where the cameras would be installed, but would not be turned on. It appears that the Cambridge Police Department feels that it’s a good moment, four years on, to raise the issue again. In the discussions over it, the ACLU is arguing for the following principles to be observed:

Involve the public in the decision making process. It is clearly wrong to put up cameras without notice. The public needs to understand the cost of cameras, their use, changes in their abilities, etc.
Establish a clear policy on data retention, access, sharing and how long it can be kept;
Establish privacy principles and make sure policy is implemented. Need robust oversight mechanisms; and
Strict safeguards should be put in place to prevent mission creep. The should be, for example, no warrantless biometric searches without appropriate safeguards.

This brings to mind debates in other communities grappling with whether to accept DHS grants. Local communities perceive DHS grants as effectively “free money for stuff”. In Concord, NH, right now, for example, the Concord PD applied for a DHS grant for a “Bearcat” armored vehicle, citing “daily challenges” from “Free Staters” and “Occupy New Hampshire” (which had not had a meeting in nearly a year). DHS said yes; and now, what police chief, when offered a free tank, would turn it down, even if it really wasn’t needed? The same goes for cameras.

There is a great deal of evidence out there on whether surveillance cameras reduce crime. The most recent overview of the academic literature, or “meta-analysis”, co-authored by Northeastern criminology professor Brandon Welsh, finds that there is no good-quality evidence that surveillance cameras reduce crime, with the exception that monitored cameras in parking lots tend to reduce, or at least shift, vehicular crimes. This is unexpected, given the enthusiasm of police departments across the country for surveillance camera projects. Such projects are often installed instead in places where they have not been demonstrated to reduce crime, such as parks and busy retail districts. Why?

The answer is, more or less, that it’s not all about actually reducing the crime rate. Surveillance cameras do appear to increase the probability of detecting people after they have committed crimes; it’s just that the deterrent effects of cameras seem often to be short-lived, so it doesn’t really affect the overall crime rate. So it’s a technology that makes the process of detection and prosecution easier. However, it may well be that people mainly care about whether cameras decrease their personal likelihood of experiencing crime. It’s widely believed that cameras do, but the research suggests that they don’t. So, if the aim is actually to reduce the crime rate, public dollars spent on cameras are wasted.

It’s hard for people to think in terms of overall crime rates. It’s natural in Cambridge for people’s memories to turn to the Boston Marathon bombings and the role cameras (mostly private) played in identifying the attackers. But here, again, the cameras that were up didn’t prevent the attacks, which is what would affect the crime rate.

I don’t have any real policy objection to private parties installing and monitoring cameras on properties that they own. But it’s reasonable to ask whether the actual public benefit of shortening the time to detection and prosecution of the kinds of relatively minor crimes that are usually caught on camera, merit the investment of time in installation and especially in monitoring and maintenance of surveillance camera systems. In Waterbury, CT, for example, surveillance cameras are being installed around the Village Green, a park in the poor and black and Latino part of town, in an effort to suppress “lifestyle crimes” like public drinking and public urination. I question whether installing and monitoring the cameras there will do much more than route more poor people into the criminal justice system, at a heavy cost in terms of monitoring and maintaining the cameras and keeping people in jail.

From a legal perspective, the Supreme Court has found that individual members of the public do not have a “reasonable expectation of privacy” (REP) while in public places, such that they can bring suit under the Fourth Amendment against a government agency installing surveillance cameras that cover public places. They have even allowed the police to install hidden cameras on private property without a warrant in certain circumstances. However, the recent ruling in U. S. v. Jones raises some questions about the REP standard. That case, which involved a GPS tracker installed without a warrant on the car of a suspected drug dealer’s wife, produced very split opinions, but a bare majority found that Jones did have a Fourth Amendment interest in the privacy of his travels over a long period of time, even if all of his travels were technically in public places. It was the finding of the pattern of his travels, not the individual journeys, that triggered a warrant requirement.

What this means is that while there’s no Fourth Amendment issue when surveillance cameras are installed and turned on, there may be an issue if police aggregate the data from a network of cameras, and run search queries that enable them to discern the pattern of a suspect’s movements over a long period of time (28 days or more). The current proposal is to have the data be retained for 45 days.

The issue of the Security Camera Policy is gaining some traction in the City Council elections, which are being held on November 5, 2013. Nadeem Mazen, who is a candidate in that election, argues that if the cameras are turned on,

“I know that in a year, we will regret this decision, and we will attribute this to the slow creep of the surveillance culture over against building our communities. It’s through community-building that we can prevent attacks like the Boston Marathon bombing. Very often, violence, on a large or small scale, can be prevented by attention and pressure from the community. Quick fixes like surveillance cameras don’t have a track record of success; they take away liberty without granting us any actual safety.”

I’d love BMGers in Cambridge to attend the community meeting, which is expected to happen in September. When I know a date, I’ll post it in the comments.

  1. Open the feeds

    In my view, the issue is more about who can access the live video feeds from the cameras than whether or not the cameras run.

    The truth is that we already live in a community surrounded by surveillance cams. They abound in private businesses, they cover parking lots and perimeters, they are literally everywhere.

    I want to be able to see the same video feeds that government agencies see. If the feeds are archived, then I want to see whats in the archive. If particular fragments are used by authorities out of context, then I want to be able to see the larger context and note the distortion.

    I think we need to accept the enormous implications of what a “reasonable expectation of privacy” means in public place. When someone is in public, they have no reasonable expectation of privacy. Photographers may take pictures. Videographers may take videos. Governments may take videos.

    I am far more concerned about what a government agency does with those video feeds than I am with the feeds themselves.

    • I am mainly disturbed about the use of data patterns from these feeds to incriminate.

      The capabilities of cameras are increasing greatly. If someone is filmed committing an actual theft or mugging on camera, then there’s no problem with the video evidence in my mind. What becomes problematic is a large searchable database of video feeds, that can be searched without a warrant to uncover “all red cars heading eastbound on Memorial Drive”, or similar.

  2. At least Cambridge seems to be engaging in open debate.

    Something of which federal officials should take note.

    • It's paid with the federal nickel.

      No free lunch. We can expect whatever they watch the feds watch, too. Will the local security for this data be as poor as the federal system? Will you be able to hack the system and follow your significant other down Brattle Street?

      Does anyone believe the surveillance is for the protection of the public and not protection of the status quo?

      Police in Washington D.C. are now using cameras to catch drivers who go through red lights. Many congressmen this week opposed the use of the red light cameras incorrectly assuming they were being used for surveillance at local brothels.” –Dennis Miller

  3. I actually agree with that.

    Councillor Kelley has been anxious to promote public discussion and is himself skeptical about cameras; it’s not his fault that subcommittee meetings are generally poorly attended by members of the public.

  4. About New Hampshire...

    You may think ‘Occupy’ is a spent force (as do I), but the free state movement is growing. This is from Mother Jones in 2011, and the gathering last June drew about 1,700 participants – http://porcfest.com/
