Some people should lighten up. It is a story, not factual so if it is far-fetched - so what. If you don't like the idea behind the story, don't watch it. I like Gerald McRaney and enjoy watching him in just about any role. Jeff Hephner used to be on Chicago Fire. The thing I was surprised at was the mistake in the scenes in the hotel room during the first few minutes. John shot the man in the white robe in the left shoulder. When they were fighting by the window the blood was on the left shoulder but when they were fighting outside, the blood was on the right shoulder. Not very good to miss something that obvious. They need someone to watch for those types of errors.
