As an adult survivor of child abuse myself, I am very much for petitioning and even far more practical action to induce change on the Catholic theater regarding this horrific and disgraceful criminal activity.
But it should be pointed out that the report that bishops should "not necessarily" be the ones responsible to report abuse (which is silly, if you ask me, because if you hear of abuse you should feel it a duty to make sure it is reported regardless of the circumstances) is itself controversial. The document the quote originated from was not officially approved by the Holy See, and the Church has made sure all involved do not follow the very odd advice (which was written by someone in the Church who has made other controversial statements before).
See http://www.cruxnow.com/church/2016/02/15/papal-commission-bishops-must-report-sex-abuse-charges/ for more information.
In the end, however, it demonstrates that upheaval is necessary to rid the Church of this evil. Apparently some people within want the status quo to remain the same, even to the point of trying to make their warped ideas official when they are not. I am not excusing the Church, of course, because there is no excuse for allowing this to happen or go on.
What I am saying is that if I were one of these bad clergymen, I would be frightened. Like the accused bishop who recently got hissed, booed, and faced the releasing of black balloons by Catholics at his appointment, I think Catholics are about to stop waiting for the Church to do anything and take matters into their own hands. Catholics can't be excommunicated or disciplined for kicking priests and bishops out of office and power, and the good Catholics aren't going to leave the Church. They will eventually drag the culprits out and show these idiots that there are more of them than there are good-for-nothing clergy who won't do anything about it. They will take power of appointments out of the hands of the heirarchy like most Prostants have done becuase it is the laity that has the wallets. Many have stopped giving monthly to the Church over this, and money talks loudest in the end...along with well-deserved cold jail cells.
