10 minutes before the murder: Expect to get an accusation of accessory to murder, conspiracy to murder and a few additional tomes of the penal code. We all know you are innocent, but you should better find a good lawyer just in case instead of wasting your last free minutes arguing on the internet.
But if you'd like to tell the fall, I'm sure some prosecutors wouldn't dig too hard to find the guilty party.
Edit: subpoena is not a criminal charge afaik is what I’m saying
