Look at it this way, this woman joined the police force, obviously feeling that it was a good career choice. We don't know her reasons for leaving, and perhaps never will.  However, her article is a collection of generalities, based on her 'interviews'.  The issue will be how she collected her data, was she objective or did she seek out those unhappy 'in the service?'  This is what will be determined when her research is subjected to peer review.  

I see many of the commenters are only too happy to jump on the band wagon, and buy into her generalizations.  As is typical with so  many G&M articles, it is sensationalized, with little or no background.  This is only her opinion, not carved in stone. 

Contrary to what she is maintaining, there are many well motivated, well educated people in policing, who do a good job, obey the laws and have a genuine interest in serving their communities. Like any organization, police forces have to change with the times, and a good many are.
