Terry,
I'm sure most people agree there can be corruption in high places and in every human institution.
But unless you have evidence of underlying corruption in a particular case, it's like saying that you've heard how bad lung cancer can be so if somebody starts coughing, they must have lung cancer.
If you do have evidence of corruption by the coroner, you have the makings of your own "honest eddie" political or media career. You won't be the first- check out Eliot Spitzer in NY, he's grown a career by demanding proper practices by and for all.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
