Supercop? Career Crim-buster? Or asinine apparatchick, a yes-man?
Or perhaps a classic example of The Peter Principle,.."..risen to the level of his incompetence"?
Was he too dependent on the American approach to policing, the "men in black" syndrome? Too close to his masters perhaps?

He certainly oversaw a few disasters, and seemed to be unable to handle the conflicting demands of his role.

Dear Max,

I certainly would not have envied Mick Kelty's
job - no matter how much they paid me. Being
Police Commissioner would for me fit into
the "too hard," basket. Not only is the job
itself tough - but the politics - and watching
your back all the time - nah, I'd rather do something
a lot less stressful. But hey - I wouldn't want to be
PM either.

They say to a man, the main advantage is that he has
relatively greater access to power, and prestige
in a top job like that - He can earn more money,
control more of his environment, and experience a
range of opportunities that are beyond the reach of
ordinary careers. But if you look at it from some
of the disadvantages - there'd be tremenduous stress
associated with a life of "living on the edge,"
repressed feelings, fear of failure, political
pressure to succeed - suffering from stress-related
diseases such as ulcers, hyper-tension, et cetera.

You'd have to weigh it all up - is it all worth it?
Obviously, I'd say - Mick Kelty decided he'd had enough.
And, who can blame him?

Whether he was a "super-cop," or not - who knows.
Sure, he's had a few "hiccups," that possibly could
have been handled better. But a few "hiccups," over
a 30+ year career - is a pretty good track record.
And whether he was pushed to resign - again, who knows?
He couldn't have been that bad at it - because he lasted
for over 30 years in the job - so I guess his record
speaks for itself. If he was corrupt - he would have been
kicked out long ago.

Anyway, as I said- the job's a tough one - he did it for
so many years - let's just all wish him a happy retirement.
I think he's more than earned it!
