Ronnie Gardocki's final fate in The Shield: granted, he was a willing participant in police corruption, but his culpability pales in comparison to Vic and Shane's actions. Especially since, under California's laws for death penalty cases, Ronnie can (in theory) be executed for the murder of Terry Crowly, even though Vic and Shane BOTH went out of their ways to make damn sure Ronnie wasn't allowed in the planning out and execution of the murder.
Isn't it also possible that Vic will have to testify against Ronnie, providing more detail into certain things he mentioned on the tape? I mean, it's not like there's a whole lot of actual evidence for Ronnie's involvement in these actions besides what Vic said on the tape. Ronnie wasn't making mistakes like Vic/Shane, so he'll probably try to anchor himself to a lawyer. That means if the prosecution REALLY wants to make sure cases stick to him, they might have to use Vic.
The military-style jackets each Shield member wears reflects their personality in some way. Seth Rollins wears a parachute jacket, because he's the high-flyer. Roman Reigns wears a bulletproof-vest, because he's the powerhouse. And Dean Ambrose wears a flak jacket, perhaps hinting he's the leader/brains behind the outfit.
