I was a 'Local Cop' assigned to direct an FBI surveillance van around the area while 'we' worked a kidnapping. I got to talking guns with the Agent/Driver. He showed me that he didn't have a gun on him but had one in a door pocket in the van. His plan was to come back and get the gun if he needed it. It was a J Frame S&W of some type, I don't remember which one?
I've been involved with the FBI just 4 times. Most of'm looked way down their noses at us because we were just street cops. Only that one driver was friendly. Most couldn't find their way to the toilet without a map.
