(CNN) -- What happened in Cairo today sends a chilling message to any journalist covering Egypt: If you speak to a group whose message the government wants suppressed, you can be prosecuted and jailed for it. In other words, you can be imprisoned for doing your job. The lengthy sentences against three Al Jazeera journalists -- Peter Greste, Mohamed Fahmy and Baher Mohamed -- convicted of aiding terrorists and spreading false information have shocked and angered many around the world. And inside the Cairo courtroom, those closest to the accused were left reeling. "Well, to be perfectly honest, my mind was blank. There was total disbelief," Peter Greste's brother Mike told me. "I can't comprehend the decision made by the court today."
