Occam’s Razor in the Criminal Courthouse

Occam’s Razor (Wikipedia) is the principle that, all things being equal, the simplest solution tends to be the best one. Occam's Razor suggests how a case should be defended (as simply as possible -- see Scott Greenfield's "The KISS Prin­ci­ple” post pre­scrib­ing a “sur­gi­cal” approach to defend­ing crim­i­nal cases); it also can help pre­dict how suc­cess­ful a defense will be.

When you have a crim­i­nal case to defend, every piece of evi­dence will fall into one of three categories:

Things you con­test (“no …”);
Things you explain (“yes, but …”); and
Things you accept (“so what?).

For exam­ple, an alleged wit­ness says that she saw your client at the scene of the crime. You can con­test this (chal­leng­ing the witness’s cred­i­bil­ity and pre­sent­ing alibi wit­nesses to say, “No, he wasn’t”); you can explain it (“Yes, he was there, but not for the rea­sons the State sup­poses); or you can accept it (“Yes, he was there. So what?”).

Another exam­ple: the com­plain­ing wit­ness in a mur­der case is dead of a gun­shot wound. Per­haps you could con­test it (show­ing that some­thing else might have killed him before he was shot); you could explain it (“yes, but he killed him­self”) or you could accept it (“Yes, he was shot to death. So what?”)

At its sim­plest, the defense of a crim­i­nal case involves only accep­tance of the facts: “Yes, every­thing the wit­nesses said is true. But so what? That’s not proof beyond a rea­son­able doubt.” These cases come up often — usu­ally because the State makes unwar­ranted assump­tions about what the law requires. For exam­ple, Weed in the Car cases are often pure “so what?” cases.

Every con­test and every expla­na­tion, how­ever, com­pli­cates your case. Com­pli­cat­ing your case is not desir­able (per Occam’s Razor and Greenfield’s Hello Kitty Safety Scis­sorsKISS Prin­ci­ple). So we can amend the list. Now every piece of evi­dence falls into one of these three categories:

Things you have to con­test;
Things you have to explain; and
Things you can accept.

Whether you have to con­test or explain a cir­cum­stance depends on the facts of the case. Some things can never be accepted. For exam­ple, an “eyewitness’s” tes­ti­mony that the accused com­mit­ted the crime must be con­tested. The ulti­mate cir­cum­stance that requires expla­na­tion is the fact that the defen­dant has pro­vided the gov­ern­ment with a recorded con­fes­sion. When the accused, informed of his right to remain silent, per­sists (against my Good Advice) in bar­ing his soul to the police inter­roga­tor on video­tape, that is a cir­cum­stance that can some­times be con­tested (for exam­ple, by chal­leng­ing its vol­un­tari­ness) and rarely can be accepted; most often, though, the only course to take is to explain it (“here’s why the accused gave a false confession”).

In keep­ing with the “cut­ting imple­ments” theme, then, here is Bennett’s Chainsaw:

The more things you must con­test and the more expla­na­tions you must pro­vide in order to mount a defense, the more likely it is that you will be convicted.

    Bennett’s Chain­saw. That’s very good. Can I bor­row it?

    Occam

    I did that to pre­empt you com­ing up with some­thing even more innocu­ous than “Hello Kitty Safety Scis­sors” to call it.

    Heh.

    Let me make it even sim­pler — “Less is more.” The less we talk, the less we have to explain, the more likely we are to win.
