For example British mainline railways require Compliance as a (psychologically tested) trait of train drivers and the lack of such a requirement was cited as a contributing factor to a death on a light rail system in a report I read years ago.
Why? Because Compliance says: This speed restriction says 45mph, I personally think 60mph should be safe but there's a speed restriction so I shall limit to 45mph even though I don't understand why.
Whereas without that some drivers will say "In my judgement 60mph seems fine here so I'll disregard the 45mph limit" and when they kill somebody and investigators ask "Why were you going too fast to stop?" their answer is that they didn't realise that would happen.
Compliance is probably a completely reasonable thing to want from regular cops, maybe even all your cops. On a TV show breaking the rules is often portrayed as admirable, but those rules are usually there for a good reason. In particular rule-obedience is very important for a community's perception of police as members of that community subject to its rules, rather than as oppressors.
