Senator Derryn Hinch being found out as he debates with Fabiano Cangelosi the merits of the sex offender registry. As Cangelosi states “ you can’t argue with the data “ ( with regard its lack of efficacy in the US where a sex offender registry has been in effect for 20 years). Hinch thought he could argue with the data, employing pseudo logic , personal opinion and anecdotes, and referenced the personal opinions of ‘ the many coppers he had spoken to’. Cangelosi merely referred to the evidence, which clearly showed its lack of efficacy. One thing that always seems to come out of this debate is the very different definitions people ascribe to the word ‘ justice’.
