if by "the police" you are referring to the typical town cops (or even large departments like the NYPD) then you are completely wrong. Apple's legal department likely consists of far superior attorneys than does that of the typical local department.
Think about it, if you are a Harvard/Yale/Stanford minted attorney would you rather go work for Apple or be a run of the mill district attorney.
(in-house work at a large tech firm is most people's dream job, and typically reserved for ultra elite attorneys) (and all this isn't even taking into consideration that Apple has the cash to retain the best law firms in the country)
Now, if we are talking about Federal Gov't agencies making requests in a FISA court, then ya ...they are going to get what they want.
and I'm ok with that, because the FBI doesn't prosecute teens for having a bag of weed. If it is a true national security issue I think the gov't should get it.
But if your Joe Shmoe local town cop wants to look through your texts to see if you sold a few of your friends some bud ...then he should go kick rocks.
