Vance looked up with a slow smile, and regarded him quizzically.
“The difficulty would seem to be,” he returned, with an indolent drawl, “that the police, being unversed in the exquisite abracadabra of legal procedure, labor under the notion that evidence which would convince a man of ordin’ry intelligence, would also convince a court of law. A silly notion, don’t y’ know. Lawyers don’t really want evidence: they want erudite technicalities. And the average policeman’s brain is too forthright to cope with the pedantic demands of jurisprudence.”
“It’s not as bad as that,” Markham retorted, with an attempt at good nature, although the strain of the past few weeks had tended to upset his habitual equanimity. “If there weren’t rules of evidence, grave injustice would too often be done innocent persons. And even a criminal is entitled to protection in our courts.”
Vance yawned mildly.
“Markham, you should have been a pedagogue. It’s positively amazin’ how you’ve mastered all the standard oratorical replies to criticism. And yet, I’m unconvinced. You remember the Wisconsin case of the kidnapped man whom the courts declared presumably dead. Even when he reappeared, hale and hearty, among his former neighbors, his status of being presumably dead was not legally altered. The visible and demonstrable fact that he was actually alive was regarded by the court as an immaterial and impertinent side-issue.[13] … Then there’s the touchin’ situation—so prevalent in this fair country—of a man being insane in one State and sane in another. … Really, y’ know, you can’t expect a mere lay intelligence, unskilled in the benign processes of legal logic, to perceive such subtle nuances. Your layman, swaddled in the darkness of ordin’ry common sense, would say that a person who is a lunatic on one bank of a river would still be a lunatic if he was on the opposite bank. And he’d also hold—erroneously, no doubt—that if a man was living, he would presumably be alive.”
“Why this academic dissertation?” asked Markham, this time a bit irritably.
“It seems to touch rather vitally on the source of your present predicament,” Vance explained equably. “The police, not being lawyers, have apparently got you into hot water, what? … Why not start an agitation to send all detectives to law school?”
