Well, maybe the age of the truth will out will change things for the better, stop certain things being swept under the carpet and turned a blind eye to by the people in the know, like Operation Yewtree enquiries, and encourage the behaviour to repeat itself.
Much as I'm a believer that there are some things I'd rather not know there is benefit in certain things not being covered up and guilty parties being able to get away with crimes, I include the phone hacking scandal and the way some of the gutter press operate in that.
