Lawyers take an oath to be present whenever large sums of money are changing hands, or when some (generally impecunious) person is given an involuntary opportunity to become a guest of the state for an extended non-cruise ship-enabled stay.
Naturally, in these situations human beings (including lawyers) being what they are, some will take advantage of the situation to, oh, shall we say, allow their fingers to get a little sticky. This natural tendency is augmented by the problem of illegal drug abuse, which demands that the public be protected from drug-addled Perry Masons.
Since the state of Florida sees fit to protect the public fisc through mandatory suspicionless drug testing of welfare applicants I propose the same rule be applied to every lawyer in the United States.
This would be done of course when applying for the bar, and every year when the lawyer pays the bar renewal fees. One could also throw in mandatory random testing. Given the huge amounts of money handled by attorneys or passing transactions they supervise, the danger of public harm from D. Ope Fiend, Esq. is at least at great as the unemployed person or the single parent on welfare.
Legal drugs, such as Rush Limbaugh's drug of choice, Oxycontin would of course be of no concern. And naturally lawyers would be free to liquor themselves up in the time-honored tradition of the bar, and of course the bench, both judicial and park.
