Good point about the leaders because Not only the leaders but the people failed to bring Jesus to justice.......................................................................................................................................
Jesus is killed through a betrayal, and so his murder is illegitimate in one more way. In every way possible he ought not to have been killed had the law been perfect or perfectly followed. Everything went wrong! The leaders failed to catch the error, and they approved of Jesus death. The High Priest did nothing to save him. Jesus shows that the law has failed to preserve an innocent person, bringing all of it into question. .........................................
Thus they all were culpable in 'community responsibility' being upon them - Deuteronomy 21:1-9; Acts 3:12-15
