Imagine this scenario: When I was 18, I openly expressed my hatred for gay people and even reported someone to the police just because they were gay. Now, 60 years later, I’m 78. Society’s values have changed a lot, and those views are now illegal and widely condemned. If someone were to find an old paper where I wrote those hateful things, I could face legal trouble and social backlash for something I once openly believed.

The point I want to make is that even if you don't have something to hide today does not mean that you won't be convicted tomorrow.

Edit: Someone else gave an example with the abortions, and that they are now illegal in many places.
