Bai Zhe was called to the police station because he was the one who’d commanded people to prepare the safety glass to put over the human rights activists and the prisoners. Thus, he was the suspect for this incident.
"Are you saying that you did it for the sake of the entertainment of the show?" asked the police.
"Correct. It's big and exciting. Besides, those prisoners were good prisoners. You can ask the prison about them. They were the ones who chose the prisoners to attend my show. They were the ones who checked everything. Who would know they'd hurt people? Apart from that, I've told the officers that we would use safety glass. They saw it, but none of them volunteered to be in there. As the prisoners, I'll have my lawyer send you the information we've gathered," said Bai Zhe.
