One.No. Many.
Pell has faced accusations over a number of years of variously talking aloud about Ridsdale, directly witnessing Ridsdale engaging in his abuse, being directly told about someone's abuse etc etc etbloodyc. He has variously been able to prove that he was overseas, or the movie wasn't showing, or he was in another part of Victoria etc etc etbloodyc.
Despite me asking many times in this thread, no one has been able to answer as to why so many allegations have been made about Pell that have been disproven (or, in other words, made up). Because victims NEVER invent accusations apparently.
