all knew Jesus hadn’t done anything wrong …. but all were afraid they would lose something if Jesus remained – priests/ authority + Pilate angry mob/ (more insurrection) & when Jesus was claimed King of the Jews he feared this would upset Caesar and he worried for his own position. etc + crowd were Jerusalem residents not outsiders (unlike Palm Sunday crowds)and did not want outsider (Jesus) to take over Jerusalem + Peter / prison .
Why hadn’t Jesus converted more people in Jerusalem into his followers the way he had converted outsiders? … need more discussion
