As someone who has been constantly annoyed for 20 years by Fortune 250 corporate IT policies, I see this slightly differently. All the confusing, contradictory, usually-non-specific-yet-sometimes-wildly-specific polices the IT department decrees come from some nice-sounding reason, usually from some white paper or consultant, or just some major screwup that caused embarrassment. But, like ISO9000 and SOX and all the rest, they inevitably wind up, as implemented, as make-work policy.

It's the same in government. Government is so large now, that every law that gets passed is now make-work law. And for all the same reasons that people with no critical thinking make it their job to enforce stupid ideas like "all code used for authentication in web apps must be written in C", people in the legal system, including and ESPECIALLY "soft" jobs like CPS, have to justify their existence by making the most work out of the least situation.

So I'll do you one better: it's the fault of politicians tugging on heart strings to pass overreaching, touchy-feely laws, that give government too much power, in order to get themselves reelected.
