Gee, Guilty or not, i would think that CASA's lawers would find the 'expert witness' and get their evidence together before handing it over to the DPP. Guilty or not, the guy should be compensated if only for the reason to make 'skull' wince. I reckon at least 10,000 penalty units in credit and a 'get out of jail card'.
CASA, useless as tits on a bull!
