Debate is swirling over an independent report into the Roast Busters sex scandal which laid the blame on the investigating officers.
An IPCA investigation found significant failings in the original police investigations into the group of 17 and 18-year-old men who boasted online about their sexual exploits with drunk and underage females.
Police began investigating the group in 2011 after girls as young as 13 complained they had been sexually violated, but no charges were ever laid because investigators believed there was no reasonable chance of a conviction.
Police Association president Greg O'Connor told ONE News the blame is with a lack of police resources not the investigating detectives.
"You've got a group of detectives overworked and having to prioritise their files every day, being called away to do other work, and the reality of it is not every victim gets the attention that they need."
Labour Party police spokeswoman said: "The police have a lot to do if they want to give security to victims in the future."
However, Police Minister Michael Woodhouse said: "I think it is very inappropriate to say that but for police resourcing, this would not have happened. That is unfortunate and I reject it and I refute it."
The IPCA's report said the investigating officers tended to approach each case on an individual basis instead of developing strategies to reduce the recurrence of what was "clearly unacceptable and, in some cases, criminal behaviour".
Police Commissioner Mike Bush said yesterday the standard of investigation in the Roast Buster cases fell far short of what he and the public expects.
