Two Police Officers shot during Ferguson Protests: Observations through TwitterTrails

The Ferguson police chief resigned on March 11th, 2015, following the Justice Department’s report about systematic bias in the Ferguson police department.  This prompted protests outside the police department, during which two police officers were shot and wounded.

Using TwitterTrails, we investigated this claim the following morning, about 10 hours after the shooting, and repeated the data collection twice over the next 12 hours to get a larger dataset.  We find that, even though we did not collect data live during the event, TwitterTrails can still reconstruct an interesting and meaningful account of the reporting on Twitter.  We capture not only traditional news media reporting, but also first hand accounts written by people on the scene of the protest (which contain information that is less visible in tweets written by the news media).  Finally, we find a very polarized audience taking to Twitter to discuss the shooting, as captured by the co-retweeted network.

Oregon High School Shooting

To describe how the Trails system works, we will go over the propagation of a recent story:

On June 10, 2014, @cnnbrk posted the tweet shown below, reporting a shooting in an Oregon high school.

Shooter killed student at Oregon's Reynolds High School this morning, police say. Shooter also dead. cnn.it/1jiGpo

Coming from a source like CNN (and a verified Twitter account), we expect this story to be true.  Will we use the Trails tool to investigate it further: possibly, to back up our assumption that it is true, and also to see how it spread on Twitter and which users influenced the discussion.
