I also noticed the police are active on Twitter so I met with Lt. Zach Perron, the Public Information Officer (PIO) of Palo Alto Police, and Lt. Chris Hsiung, the Public Information Officer of Mountain View Police, to talk with them about Twitter and social media.

There are almost 18,000 police departments in the USA. Several thousand are using social media for investigation and outreach. They do investigation, of course, but community policing outreach is more important: they see social media as a way to improve transparency. It allows the police to have a personal presence and collaborate with the community. They can reach out to the public and the public can also contact them.

The Boston Marathon Bombing was a watershed moment because it was the first time that the international community was able to receive timely and accurate information in a major critical public safety situation directly from a police agency via social media. In the general panic after the bombing, the web was filled with rumors. The Boston police used Twitter to update people about the search for suspects. When the suspect was finally surrounded and captured, the police tweeted updates every few minutes. Boston Police’s use of Twitter created an expectation among the public that if a terrorist event happened in their community, the police in their jurisdiction would be on social media and do what the Boston police did. It raised the bar for police agencies.

Social also allows police departments to bypass the media and reach the public directly. Newspapers and TV/radio news often spin stories to make them more dramatic, which attracts viewers, which increases advertising revenues. Crime in the US has fallen steadily for more than 30 years to record lows, but you won’t know that if you watch TV news.

When the police told the media that they were going to start using social, the media said please, don’t do that, it takes the news away from us.

Previously, the police held press conferences for the news media. While police still conduct press conferences in major cases, many now post routine press releases directly to Twitter, Facebook, and Google+. By creating their own broadcast capability, the police are able to talk directly with the public when something is happening. The result is greater accuracy because the news media can’t spin the story. Instead, the media now often retweet the police tweets. For example, a press release tweeted by the Palo Alto Police Department can be retweeted by the media and can reach 150,000 people within moments, giving the public the opportunity to read accurate information directly from the source.

How does this work? A few months ago, two Palo Alto police officers stopped a car on a busy downtown street at lunchtime. The driver then drove away from the stop, crashing into multiple cars, and then fled on foot. It created quite a scene. The cops ran after him for a few blocks. However, people in cafes and restaurants began tweeting about police car chases, hostages, guns, and so on. The police were able to immediately reply by Twitter that none of that was happening. It was just a foot chase. They can clarify, correct, and update, which calms the situation and prevents the spread of misinformation to the public.

Social also allows police to be seen as human. Some of the tweets are really funny. One day, they tweeted they would set up a speed trap at an intersection. After they caught one guy, they tweeted he should have been following the cop’s tweets!

Coffee with the Police.

Coffee with the Police. Via Twitter and Nextdoor, the Palo Alto Police invited neighbors to meet at a coffeehouse. Two hours of chatting about what it’s like to be a cop, questions about recent burglaries, etc. It’s great to realize police are people too who care about the community. She loves being a cop. At center, blond hair and uniform, is AJ, who led the event. To the right of her, blue shirt, behind the tree, is her evening supervisor. Both cops are women.

To see what the police are doing with social media, you can follow Lt. Zach Perron at @PaloAltoPolice and Lt. Chris Hsiung at @MountainViewPD. Both of them also tweet about law enforcement’s use of social media from their personal accounts at @zpPAPD and @chMtnViewPD.

The Mountain View Police uses a blog (MountainViewPoliceBlog.com), Facebook, Twitter, and Google+. They also use Nixle, which lets police send SMS alerts to their communities. They use YouTube for videos and Pinterest to post photos of lost and found items, their police dogs (great pixs!), the officers, and other items (go to pinterest.com/mountainviewpd/boards/). Both Palo Alto and Mountain View police are also using NextDoor, a social media site that’s based on neighborhoods.

In the San Francisco Bay Area, over 50 departments, including police, fire, ambulance, and other emergency groups share information through the Bay Area Law Enforcement Social Media Group (#BALESMG). Other cities are encouraged to contact them to learn more.

There’s also IACPSocialMedia, a central resource for social media for the police. Many of the FAQs and presentations can be used by your organizations for your social media strategies.

You may wonder why the police are so active in social media. Many of the city departments are using social media, but the police get the attention: they have the SWAT teams and the dogs, plus people like to watch cop shows.

Several companies are building software for the police. For example, BrightPlanet offers BlueJay, which lets police monitor tweets within their community. They can mark off an area on a map, select terms such as #meth or #shooting, and get alerts when these words show up in tweets in their selected locations. The police can also add a list of users to monitor. BlueJay delivers the tweet text, the type of device that was used to post the tweet, and if it’s enabled on the device, the GPS location. By clicking on the user, the police can see his past tweets, posted pictures, and tweet habits. The police can download the most recent 10,000 tweets that match the users, keywords and place names in their watch list.


BrightPlanet’s BlueJay is a Twitter monitor for the police. A police officer can select the city, add a list of keywords and users, and watch a live feed of tweets that match those criteria. When someone sends a tweet with a keyword, there’s an alert tone and if GPS is enabled on the device, a dot shows up on the map. The officer can zoom down to street view to see the location.
