If a Fourth Amendment warrant can be evaded by just buying an IPhone we’re doomed anyway.

The Bill of Rights shouldn’t be a joke.

[Protect the Bill of Rights]

If we are required to proactively make all of our personal information available to the government or LEO just in case they might want to access it, the 4th Amendment means nothing. The right to privacy no longer exists. The terrorists will have won, while they move on to other means of encryption.

Owning an iPhone is not evading a warrant. If the government serves a warrant, the owner is compelled to obey. If he does not, a court can compel him. If he still refuses, jail him for contempt.

Good point.

Let's take a look at that pesky Fourth Amendment:
"... no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."

What place does the government wish to search? What items does it wish to seize?

There is a proscription in the Bill of Rights against self-incrimination. When it becomes possible to scan a person's brain to reveal their thoughts or memories, will there then be nothing exempt from search and seizure?
