Why does James Comey hate cops?

"A hunky Baltimore police officer has been inundated with marriage proposals after a photo of him cuddling a stray kitten he rescued and then adopted went viral....  The image [of Jon Boyer with friend] received more than 4,000 likes and several hundred comments praising his selfless work -- and handsome looks." (Daily Mail) How many politicians got on his case for this unseemly publicity?

We're accustomed to various privately funded agents of fascism—the heads of police benevolent associations, the radio-talk Ciceros—issuing blackmail threats on behalf of the police, to the effect that if the behavior of cops is subjected to some kind of public scrutiny cops will just refuse to protect us.

And I generally discount it, because I believe the responsible figures who tell me that the vast majority of police officers are serious and dutiful and good people who would never dream of conducting their work like a protection racket, and have no reason to fear seeing it exposed. At least I'd like to believe them, but it's somehow not very easy to find out how true that is.

But I get taken a little aback when the director of the FBI does it, as reported today:

Mr. Comey lent the prestige of the F.B.I., the nation’s most prominent law enforcement agency, to a theory that is far from settled: that the increased attention on the police has made officers less aggressive and emboldened criminals. But he acknowledged that there is so far no data to back up his assertion and that it may be just one of many factors that are contributing to the rise in crime, like cheaper drugs and an increase in criminals who are being released from prison.
