TIME’s Nancy Gibbs and Lev Grossman have published the full transcript of a Tim Cook interview that will be the subject of the magazine’s March 28 cover story.

It’s a lengthy interview, with Cook discussing a variety of issues related to the FBI’s requests in the San Bernardino case. Cook comments on his views on encryption in the modern technological landscape, how the US Congress should approach this debate, and why Apple views the FBI’s demands as a threat to civil liberties. It’s a great read with some fantastic passages.

The thing that is different to me about Messages versus your banking institution is, the part of you doing business with the bank, they need to record what you deposited, what your withdrawals are, what your checks that have cleared. So they need all of this information. That content they need to possess, because they report it back to you.

That’s the business they’re in. Take the message. My business is not reading your messages. I don’t have a business doing that. And it’s against my values to do that. I don’t want to read your private stuff. So I’m just the guy toting your mail over. That’s what I’m doing. So if I’m expected to keep your messages, and everybody else’s, then there should be a law that says, you need to keep all of these.

Now I think that would be really bad. I think it would be really bad because in order for me to keep them, I have to have a way to see them. If I have to have a way to see them and a place to copy them, you can imagine—if you knew where the treasure was buried at, and everybody else did, then it puts a bull’s eye on that target. And in the world of cyber security, the last thing you want is to have a target painted on you.
