No problem mate, a professional registered website on the True Story of Ronald Ryan is almost completed. Purrum won't be able to contribute trash, lies, allegations, accusations, opinions, views, on the Ryan case. 
Purrum's infamous promotional book-for-profits The Hanged Man (pages 221 & 222) confirms Purrum as a compulsive and manipulative liar. That's a fact!
The book states; The discrepencies in eyewitnesses evidence were substancial and wide-ranging. Each of the fourteen eyewitnesses testified different accounts of what they saw. Some eyewitnesses testified seeing Ryan to the East of Hodson and some eyewitnesses testified seeing Ryan to the West of Hodson. Some eyewitnesses testified seeing smoke coming from Ryan's rifle, although it was established by an expert on forensic ballistics Senior Sergeant Colin Letherbarrow, who testified that the cartridges used were of a smokeless variety. (Eleven eyewitnesses testified they saw Ryan armed with a rifle. All fourteen eyewitnesses testified of hearing one single shot and Hodson fell to the ground. More significantly, only FOUR eyewitnesses testified actually seeing Ryan fire a shot. The was no contest that the evidence of each eyewitness were very contradictory. Purrum's infamous book goes on to describe the discrepencies in the prosecution's case, eg. the lack of scientific forensic evidence, the vital missing pieces of evidence, the downward trajectory angle of the fatal bullet, and prison officer Paterson testifying he fired the single shot that was heard by all eyewitnesses. 
Thank you and Good Luck with the ongoing lies!
