Why is right for an MP to swear but not use the word pleb to a policeman?

In full: Police log detailing Andrew Mitchell's 'pleb' rant
Here The Daily Telegraph publishes in full the 442-word police log of the incident in which the Conservative Chief Whip Andrew Mitchell abused police officers.

Whilst on duty at *** tonight (Wed 19th Sept) on a 1400-2200 hrs between the hours of 1800-2000 I had to deal with a man claiming to be the chief whip and who I later confirmed to be such and a Mr Andrew MITCHELL.
Mr Mitchell was speaking to PC ******** demanding exit through the main vehicle gate into Whitehall. PC ******** explained to Mr MITCHELL that the policy was for pedal cycles to use the side pedestrian exit. Mr MITCHELL refused, stating he was the chief whip and he always used the main gates.
I explained to Mr MITCHELL that the policy was to use the side pedestrian gates and that I was happy to open those for him, but that no officer present would be opening the main gates as this was the policy we were directed to follow.
Mr MITCHELL refused. Repeatedly reiterating he was the chief whip. My exact explanation to Mr MITCHELL was "I am more than happy to open the side pedestrian gate for you Sir, but it is policy that we are not to allow cycles through the main vehicle entrance".
After several refusals Mr MITCHELL got off his bike and walked to the pedestrian gate with me after I again offered to open that for him.
There were several members of public present as is the norm opposite the pedestrian gate and as we neared it, Mr MITCHELL said: "Best you learn your f------ place...you don’t run this f------ government...You’re f------ plebs." The members of public looked visibly shocked and I was somewhat taken aback by the language used and the view expressed by a senior government official. I can not say if this statement was aimed at me individually, or the officers present or the police service as a whole.

I warned Mr MITCHELL that he should not swear, and if he continued to do so I would have no option but to arrest him under the Public Order Act, saying "Please don’t swear at me Sir. If you continue to I will have no option but to arrest you under the public order act".
Mr MITCHELL was then silent and left saying "you haven’t heard the last of this" as he cycled off.
I forward this to you as all officers were extremely polite to Mr MITCHELL, but such behaviour and verbal expressions could lead to the unfortunate situation of officers being left no option but to exercise their powers.
I write this for your information as Mr Mitchell’s last comments would appear to indicate that he is unhappy with my actions.
I have recorded this fully in my pocket book.

Because by using the word Pleb he is defining himself as part of the aristocracy and the Officer as not. Though the original latin term could refer to quite rich people who just were not Aristocratic, today it is generally taken to mean uncultured and unsophisticated. So by using the term PLEB he is reinforcing his alleged previous statement that" you learn your f------ place" inferring his own automatic superiority in all situations even in a situation where he is clearly not.

Haha A circle of ironies.

The Polebs get their power given to them by those who judge others from a higher position. ;D

The Conservative government really are alienating themselves because they are seen as out of touch with white upper class males from Oxbridge education making up policies on the poor people and letting off the rich because they believe their money will trickle down to the plebs and keep them happy.
