Manhattan DA: iPhone Crypto Locked Out Cops 74 Times

I'm not a lawyer, but I guess I don't understand the problem:

1. DA asks court for an iPhone search warrant because a crime may have been committed.

2. If the evidence looks strong, court issues warrant to search phone.

3. DA serves warrant to phone owner.

4. If owner doesn't unlock phone voluntarily, owner is in contempt of court and subject to legal sanctions.

Why does Apple need to get involved?
