Maybe I shouldn't put my private data on MY smartphone?! What?! Did you even think while you typed that?
It's my bloody right to put whatever I want on my smartphone, home computer, etc. and have it remain private. You miss the point of all this: almost all of us have nothing to hide; that doesn't change the fact that the government has absolutely zero right to invade our privacy just to catch a few bad apples.
Also, if history has told us anything, governments cannot be trusted. The fact that the US government had a huge and, arguably highly illegal, surveillance program already in place unbeknownst to most Americans just shows the tip of the iceberg. But hey, if you don't want privacy and fundamental protections to your rights and freedoms, fine then...you're on the right path to losing them anyways. I hope you sleep well at night knowing how "secure" you are because the government has the potential to watch everyone's every move.
There might be some good arguments on either side of the fence for this discussion, but yours certainly isn't one of them. Your argument of handing someone's phone to Apple to have them unlock it is exactly the problem Apple is warning about - if Apple builds a backdoor, others, including the government itself, will be able to exploit it. Once the door is open, it will be nigh impossible to really police who can get access. Apple, Adobe, Microsoft, Google, etc., already face system security threats and exploits all the time. Can you imagine if they purposely built in a door for this kind of thing? My God...
