How can cops combat the rise of crime broadcast on social media?

In April 2017, a man named Steve Stevens murdered an elderly man out for a walk. Stevens then posted a video of his crime on Facebook, where the footage remained visible for hours.

Jim and Doug discuss the prevalence of these types of incidents, as well as some ideas about how to deal with them from a criminal prosecution perspective.
