On April 16, 2015, police officer Jesse Kidder encountered a murder suspect named Michael Wilcox in a suburb outside of Cincinnati, Ohio. What happened next was caught on video and surprised a lot of people, including police. And the incident tells us a lot about how these videos have changed us.

On Dec. 28, 2014, Robert "Bobby" Smith shot police officer Tyler Stewart and himself in Flagstaff, Arizona. The video of that shooting has since taken on a life of its own. Police use it to talk about the dangers they face every day. Other people see it as a painful loop that will never stop playing.

Chris (@stoneymonster) and Elecia (@logicalelegance) answer listener emails. Get your entries in for March Micro Madness, the matches start very soon. The short story Elecia finds most memorable is All Summer in a Day by Ray Bradbury. We mentioned Procopio who teaches microcontrollers at the Monterrey Institute of Technology and Higher Education ITESM (site, wiki) Hector sent up the IEEE Code of Ethics, a good high-level set of rules.

On Sept. 14, 2013, Jonathan Ferrell was shot and killed by a police officer named Randall "Wes" Kerrick in Charlotte, North Carolina. Like a lot of recent police shootings, much of what we know about what happened comes from a video. But the way you see that video depends on who you are.

So often, it seems like there's a new video of a deadly police encounter in the news. But those videos only tell us part of the story. Embedded is back March 9, and we'll have three episodes that each tell the story of a different video. We'll find out what happened before, during and after. And we'll explore what that tells us about policing in America.
