I think that's a very uncharitable and inaccurate view of the Pope. He is dealing with a 50 year crisis going back to John XXIII that spans the globe. There is no way he going to be able to just clean that all up in 4 years of his Papacy. 

Also he has tried to take actions and steps and under his Papacy some of the first prosecutions of abusers have taken place such as the case reported here on NCR of the priests from El Salvador on trial right now due to his reforms. 

So saying "he's sorry they got caught" is a load of rubbish. It's easy to throw stones at the sidelines and criticize when you're not in the position of Francis inheriting a mess of global proportions as well as having to deal with entrenched resistance from the Vatican.
