undivided attention? being in the courtroom doesn't make you any less distracted or harried. the lawyers are handling multiple cases at the same time. the judge is probably doing crosswords up on the bench. some of the jurors are probably thinking about where to eat for lunch, others decided the case soon as they saw the defendant walk in the courtroom wearing jailhouse orange. and That's just for the 10% of cases that actually make it to trial.

I agree that the style of the typical errors differs, although there are definitely cases decided by some stupid mistake made when collecting evidence.

But even when I try and test I don't hit 1 bug per 2000 lines of code. For example, I wrote a collapsing futures library for obj-c [1]. It only has about 1000 lines of non-test non-header code. The code is tested, I've used it in projects, and I re-read it now and then trying to come up with ways to break it. Is it reasonable for me to lay 50:50 odds on a bug being present? I don't think so.

(Are you the owner of the github repo statsd.net [2]? `someGraphiteLine.Equals(null)` returns false but `someGraphiteLine.Equals((GraphiteLine)null)` throws an exception.)

They are errors of intent and bigotry. Intent on the part of over zealous prosecutors, and simple bigotry of human nature.

A public defender may have in excess of 200 cases. Some defendants spend fewer than five minutes with their attorney. Some counties bid out public defense at fixed prices; in 2007 Virginia capped public defense for 20-to-life felonies at $2085. Bach[1] documents a defender who was paid $42,150; in four years he took fourteen cases to trial, out of 1493; on one day he represented 89 defendants, all of whom plead guilty or had their trials deferred.

These numbers compare unfavorably with the cost of software contracts, the typical pay of software developers, and the amount of time that a line of code gets to spend with its developer[2].
