The F.B.I. 

Indeed, yes, I remember this series... and I don't believe I've seen it in reruns myself, although I'm aware of it being rerun on stations I could not receive. I think I tuned into this two to four years before it came to an end in 1974. I am old enough to remember that the show was produced with the cooperation of the director of the FBI, whats-his-name, um, J. Edgar Hoover. The last season or so had different names since Hoover had died.

I really liked the way they set up the episodes, showed the crimes being initiated, the charges being shown on the screen. The oft-repeated scene of showing Erskine listening on the phone at the same time as a crime victim or victim's family. Erskine going under cover, like masquerading as a blind man. The high school boys trapping a friend in an old mine shaft or whatever and discovering, just after they were arrested, that the field had been leveled and buried with fill.

This would be good to see on DVD, but I'd be happy if it was rerun on one of the cable specialty channels.
