If all someone did was watch lawyer shows or go to lawyer movies or read most newspaper stories about lawyers, he or she might conclude there are only three kinds of lawyers: prosecutors, criminal defense attorneys and lawyers who practice in big firms.

Or at least in firms of a certain size. (It was never really clear to me how many lawyers practiced at that firm on “L.A. Law” — it seemed to be about a dozen, but who were all those people behind those closed doors in the hallways and leaning over the secretaries in those cubicles in the background? They couldn’t all have been Internal Revenue Service agents auditing Arnie Becker. Possibly private investigators for estranged husbands.)
