If BE was a suspect in an attempted rape and had been on the radar than WAPOL screwed up IMO. They could have at least cross referenced all known suspects with what type of cars they were driving. I mean, he fit the age and the assault was in the same state, just a few suburbs away. Everyone knows that rapists / killers escalate so they should have been looking at pettier sex crimes from earlier years. I find it hard to believe he was right under their noses for 20 years and they didn't bother to check all previous sex assault suspects. They had the resources. Also, if BE had been questioned back in 1988, surely he wouldn't have been as brazen as he was? He was a Telstra worker and kept his vehicles in plain sight. The link to the CSK is obvious. He must have been fairly confident that they wouldn't be looking at him.
