A mistake the MP made was: he was trying to talk to the pumped up deputy too much. The deputy interpreted his talking as disrespect and a lack of submission to his authority, which apparently got him angry.
And this is surprising(?) COPS are all about control. Can you say
Law Enforcement Officer out loud. The day of the Peace Officer is dead. The day of the Enforcement Officer is alive and thriving. Enforcement demands CONTROL!
That said:
The problem is not that the cops don't need control but that many either don't know how to exercise it effectively or exercise it just because they can. One is a symptom of poor training and can be corrected. The other is pure jack booted thugism and once identified needs to be exorcised as quickly as possible. Unfortunately, anecdotal evidence indicates that the number of incidents occuring today because of it is on the rise.
I am very conflicted...
On the one hand, in any situation where the police are confronting someone who they do not know to be a law abiding citizen it is in their best interest to maintain control of the situation, for the citizen's safety and their safety. The way they go about maintaining that control and the level of violence or implied violence that they use is of course purely situational.
On the other hand, at the macro level how are society's best interests served? Whose interests should have priority - the citizen's or the LEO's? It seems that these days the LEO's safety and best interest are placed above those of the citizen. In the short run this leads to fewer dead or injured LEO's. In the long run it takes us down the short road to becoming a police state.
IMO this is fundamentally wrong. A LEO is kind of like a soldier - he signs on for a dangerous job knowing he may lose his life in it's performance. THUS the citizen should always get the benefit of the doubt - even at the cost of a LEO's life. Sound harsh? Don't want to risk losing your life in the performance of your duty - then don't be a LEO.
The cop in the video lost control - probably because he was scared after a long chase, was improperly trained to take control of this type of situation and probably lacked experience. He seemed really afraid and fear combined with adrenaline does funny things to the brain and the deputy IMO was probably a victim of both.
In the absence of quality training and experience, and given the
LEO is the boss no matter what attitude so prevalent today, the scenario that occured was almost inevitable, has occured in the past and will no doubt be repeated in the future.
It - as another poster postulated - probably occurs more often than we know simply because when all is said and done it's usually the cop's word against the dead guy's.
