> Some say "i do nothing illegal" "have nothing to hide".

I hate how pervasive this argument is. I'm so tired. Sometimes I wish they'd get the total panopticon they want so much. I'm sure the government will be able to find some crimes to hang them with.

The best response is always:

"That's not up to you."

When people claim they have nothing to hide, always point out that's not up to their determination. That freaks them out, it disarms their shrink-from-confrontation move.

And you can point it out super fast, in a plain six word statement. No need to launch into a deep discussion unless prompted.

Alternatively, simply respond with: yes you do. When they reply: "what?" - "every single thing you have ever done wrong across your entire life." Everybody has done something they would prefer to keep hidden, the cowards just lie about it.
