Trying to encourage criminals (and others) to avoid buying Apple phones or Android phones without foreign modification. Plenty of foreign companies will gladly sell Android phones with security modifications that McCain doesn’t like.

He’s trying to do things that will damage US businesses in order to stop bad guys who will get around his efforts in any case. That’s the kind of short-sightedness you usually see in Ds. Then again McCain often looks like a D.
Yes anti-Fourth Amendment encryption will have to be banned.
However secure encryption that can be accessed by warrant is quite doable and affordable.
Won’t be as cheap and easy, but needn’t cost much more.
