I'm waiting for the episode where Gene Hackman does a cameo to smack Danny up the back of the head, telling him his tactics are going to get him jammed up. Naturally, Frank will be swept away in the fallout.
Erin will knock Lady Justice off her pedestal and put herself on it.
Henry gets to mumble "If you'd given me more lines, I could have warned you this could happen".
Perhaps, if the series continues, a little more emphasis on cases might be brought in on occasion. The family is why the show has had so much success. We don't need another 'cop show'. But policing is fading into the background.
