I'm glad he's come to this conclusion, but there is a reverence in the tone that is exactly why it's taken him so much longer than lots of other people and organizations who have been advising the same. Decades longer, even.
Of course, law enforcement isn't the enemy. That goes without saying. The enemy is every law enforcement officer and/or politician who commits or defends the kind of bad police work that negatively affects the lives of innocent people. The enemy is the culture that encourages even good police to turn a blind eye to that kind of police work. Both are easy to spot and always have been.
"Today?" This is very surprising coming from someone who has a prominent place in a school of journalism. That police officers and organizations have been acting in atrocious ways while regularly victimizing the citizenry has been well documented since there have been police officers and organizations.
Which is precisely why you don't keep a close eye on the police (or any other powerful organization) "reluctantly." You do it as an obvious response to a serious long-term problem. You do it as a reasonable safe-guard against potential danger.
Good citizens don't "trust" the part of the government that can taze or shoot you with relative immunity. No good police officer wants to be "trusted" simply because he or she is a police officer, but rather because he or she has a record of positive behavior on the force, and, quite reasonably, because any officer who behaves negatively is removed from the force.
"Trust" is the mortal enemy of good governance (not to mention journalism).
