Columbo was a success because (after the first few episodes) we saw the humble, apologetic and fumbling detective who was berated by the guilty finally catch the big nasty crook. Some have criticized the accuracy both legally, and sometimes medically, etc that led to handcuffs, sometimes myself included but you just have to go along with the programs for the entertainment they provide. Accurcy is in many cases is given a backseat to logic so just sit back and pretend - enjoy the long running series fo what it provides.
