"Just doing his job"

Reese Witherspoon was arrested for disorderly conduct.  What she did is what a lot of people did, she didn't think, she spoke like a privileged bitch and forgot that she had too much to drink.  I can see that, who hasn't said something stupid in the heat of the bottle?  What bothers me is the comment made later when she apologized.  She said that he (the arresting officer) was "just doing his job."
Just doing his job.  The job he Just does requires quite a bit more than you think Ms. Witherspoon.  His job requires that he has to deal with assholes and drunks and those that would like to kill him and he must be able to distinguish between the three in a split second because he wants to go home alive every night.  In just doing his job he must take into consideration that while he has you pulled over because you made to stupid decision to drive drunk when you clearly have the means to call a cab, he must also be aware of any car that may try to play a game of chicken with him on the side of the road.  He must keep an eye on you because you want to get out of the car and create a distraction.  Granted you are only an academy award winning actress, but you could have been a couple of druggies, armed and a little bit tweaked.  He doesn't know for sure because when he is just doing his job anything can happen. 
When you just do your job, Ms. Witherspoon, there is a very low chance that you will be hurt or killed.  Thousands of dollars go into safety measures to prevent your injury.  This man, he wears a vest.  Oh he is armed with a gun and flashlight, maybe a taser and he will have backup, but in the first moments, he goes it alone.  He has to approach every situation with a degree of caution.  You have a team of people looking out for you.  He has his intuition, his gut, maybe a partner.  He has to go from zero to sixty in a split second.  Imagine what that does to him-  you get to read the script, you know when the fake gun is going to be shot, you know when the car is going to crash into the car you were pretending to be riding in- he gets none of these warnings.  He has the tools of his job, what is on his belt and in his heart and mind.  Imagine what that repeated race of heart and adrenaline rush does to his blood pressure and digestive tract.
There are a lot of people that are just doing their job.  I am one of them.  And in this week, we saw a whole lot of people that aren't just doing their jobs.  Take a look at the video and photos of the police in Boston, the firemen in West, the soldiers everywhere.  These people are not just doing their jobs.  Oh, they may say that because for the most part, they are ordinary people with extraordinary senses of purpose and responsibility.  Those people that rushed into a burning fertilizer plant knew full well that this wasn't a controlled explosion that was going to be added later by computer, they knew that there were people inside that needed help.  Those officers in Boston didn't know where that kid was, but they knew he had nothing to lose and that is the worst kind of hunt to be on.  The blood was real, Ms. Witherspoon, and it wasn't just blood, it was the blood of innocent people and it was the blood of two of their own.  Even here in little ole Des Moines, for nearly thirty hours, ours were out there just doing their jobs.  For me, my Saturday night date was cut short and my entire Sunday plans were put on the shelf because my husband just had to do his job.  Oh, and he left at 1230 am to go just do his job again.  That being said, most of those out there on this call had just been doing their jobs a lot longer than my own husband so what sounds like anger to you is actually appreciation that mine wasn't gone quite as long and was able to get some rest.  And this weekend in Des Moines was nothing compared to the four days in Boston where those were just doing their jobs.
So your husband drove drunk and you were a bitch.   We will all get past that, but you need to find a better way of expressing yourself.  You need to check with a script writer to find the words that more adequately express what this officer was doing.  Because I promise you that is just wasn't his job.  It was his way of life, it was what he lives and breathes so that he can live and breathe.
