The Government is not giving you the phone or making you buy one so if you are so inept that you can't come up with a secure passcode you can remember or you're so lazy that you need to be able to only look at your phone to unlock it you are the problem in this situation not the police.  It's an easy fix, don't buy the phone if you're often in situations where the police want to look at your phone.  Apple will lose money introducing technology no one wants or needs.

Ah but we know that people won't put blame at the right place.  Millions will buy it and then blame and sue the police for violating their rights.  I guess that is one way to get around the $1200 price tag ;)
