Have written about the dedication of criminal defence counsel, such as here and here. Turns out that there are some who pose to the fashion, though readily recognized as such by those who need no posing.
Comment of a colleague in relation to someone who shows up in the courts from time to time, being the expert criminal defence counsel in his own mind:
He’s out there on the frontier, as a rogue practitioner.
As charitable a description as possible, under the circumstances.
