I respectfully disagree the government had anything to do with Columbo being killed. There is absolutely no way after all this time that had the government had anything to do with that killing and a few of the others that no credible person with knowledge would not come out and announce it. not in this day and age of the narcissism running rampant on social media nd T.V....NO WAY. Two informant's in particular come to mind I think would've come out M. Franzese and Sammy the Bull with information about it if true. Just zero chance anyone around with information would keep any of it to them selves. It was a mob hit all the way.
