The Trials of O'Brien

I have little detailed recollection of this show - I was only 8 or 9 when it aired - but I remember liking it a lot. I remember one episode that opened with O'Brien having a casket/corpse brought into a courtroom (cannot recall why), much to the annoyance of the judge. It must have been a well-written series, as that would explain why I liked it so much. And Falk, of course, was great. He HAD to have borrowed from this to create the "Columbo" character. I also very much recall the jazzy opening theme! Pity we don't see shows like this aired on TV Land or some other cable venue. Why not?
