So a few years back I was at a police department promotion ceremony and began chatting with a guest who was an ATF civilian analyst. Every gun story he told was fascinating. Every insight he had on firearms was spot on. He was good humored and friendly, so I asked him right there, would you ever consider coming on the Hey Chaplain podcast? We can talk guns, we can talk the ATF, I just want to get you on the show. He was very agreeable, but he said, we'll have to run it by legal first.

Three years later…

We now have Mark Brock here to talk about crime scenes, firearms and ammunition, working for the ATF as a retirement job, and which sidearm is best for police officers.
