The movement to arrest the pope is growing, & "sovereign immunity" doesnt protect for crimes against humanity?

I've been harping on about this, reading all I can avidly. The fact is the Pope signed doents when he headed the diocese that dealt with crimes within the Catholic church. By doing nothing, to protect the Catholic churches imagined good reputation, he is, in my mind as guilty of causing the children's suffering as the perpetrators. Why all the protection? He's just a man, a man who aided and abetted the harm caused by paedophile priests.
