How do the opening scenes of three police dramas establish or challenge the stereotypes of the police?

In the TV 'New tricks' the first scene that we can see is a bunch of adults in what from the mise-en-scene we can only assume to be a detective department due to the amount of administrable sat around them with books and a white board in which they all appear to be facing. They're dressed in fairly formal clothing however there is a clear divide between the two younger character's in their leather jackets and skinny jeans too the older generation who appear to be in these old fashioned suits and haircuts. The programme 'Heartbeat' has a fairly similar environment to this with its small group of people however this preticlar episode shows the establishing shot as in what we can assume is a village pub where everyone knows each other. The scenes used throughout the first 5 minutes do show three different locations that really show the slightly quicker paste that this one has. 'Ashes to Ashes' stands out in the way that although set in the 80s, seems a lot more of modern setting with lots of quick editing and transitions. Because this was set to be 20 years ago, the director would have put a lot of attention towards the mise-en-scene to really fit with this. Things like the cars they own, hair cuts they have and eighties style clothing gets in straight into our heads that its not meant to be in current times. Its set for probably the middle aged so alot of them watching will be able to relate to the mise-en-scene as they would have been in there prime in the year its set.

The music used in new tricks is all very jolly and exciting, it straight away puts an audience expectation on what age its aimed at and that sort of hints that the whole show, even if it is a show about the police, it won't be an all action one and that really in a small town it's set in the police don't have a lot of crime to deal with. Similar to new tricks, heartbeat uses a lot of iconic music and interestingly with this one the rest of the sound is diagetic and more dialogue driven therefore the words are seen to be as important as putting sound behind it when the characters are talking. With ashes to ashes, as its set in the 80s the director choose to go with the obvious choice and use 80s music that fits in with the all action that's going on. A variety of music has been used in just the first 10 minutes to go with what's going on in the scene.

With new tricks, the shots are very quick and often show more then one person in the screen. When they are having the disagreement about buying the car it shows three people on one side of the room and three on the other and the movements go from either side to sort of show the rivalry that's going on in the room. With heartbeat the editing is all fairly show with lots of close ups and over the shoulder scenes; especially in the dinner and car scene. The whole clip seemed to focus on the eyes, as from watching on the screen i felt mine were drawn to these and what there doing help us to understand the story well. Ashes to ashes uses very quick editing and tends to use more long shots to enthisise the action that is going on.
