I thought I'd reorganise the information in this Peter Oborne post.
I plotted the number of times each newspaper group reported on the phone-screwing case against the number of times they were caught paying for information. Even I was surprised when the R^2 correlation came out as 0.94 - a near perfect inverse relationship. The shittier your newspaper's general conduct, the less news it carried. If some twit at the Observer hadn't tripped over his cock, it would probably have been a linear relationship.
