Most of the other reviewers have detailed very efficiently most flaws in this episode, and it has a few, more than a lot of other episodes. The more I watch of Columbo, the more flaws I see. And there is a flaw I finally saw in this one that was not mentioned before. Columbo is reading the medicine log book when Montoya angrily tells him he will have to get a court order to read the book so what does the great sleuth do? He keeps reading the book and Montoya all of a sudden lets him and even answers some questions by Columbo about what's in the book. Also that ending is ridiculous - don't ever freeze in front of a raging, attacking, killer bull or you will go to jail. LOL.
