Would Perry Mason defend someone arrested by Lt. Columbo?

[The Magistrate]

12. Would Lt. Columbo Arrest Someone Who Had Perry Mason For a Lawyer?

That, Sir, might be a better question. It always surprised me that Lt. Tragg or Mr. Berger went ahead with the warrant once they had been informed the person they sought to arrest and convict was a client of Mr. Mason's. It neever turned out well for them, and was often downright embarrassing.

I would like to have seen a Columbo where he's called to some nondescript alley past midnight to see there a young gang-banger's corpse with two rounds to the head and not one soul around, a la The Wire, and see how he makes out with that...
