You are constitutionally protected from commenting, speaking, or writing statements, giving a confession, or simply admitting to anything. You must now be patient and wait. Nothing you say will be believed unless you say what they demand, I CONFESS, I'M GUILTY, I DID IT, I WAS WRONG. Don't be more stupid, just be calm and quiet.
You have the right not to incriminate yourself, or say anything, except I'm going to exercise my right to remain silent. Then no matter what is said or done by anyone you simply smile and say, sorry no comment. Yes, some will bully and threaten, they might even terminate you, but by saying nothing you don't make things worse.
In many cases, unless a person confesses, nothing extreme will happen. If it does happen anyway, at least you didn't snitch on yourself. So, stay strong, stay calm, and remain silent. What's done is one, and words you say won't be used to make it worse.
