"He said, 'Are you aware it's actually illegal to pay a window washer?' and I said, 'Well, no, I certainly wasn't aware, it's news to me to be perfectly honest with you.'
"I said to the guy, surely you could caution me, because … I wasn't aware, I know that's no excuse … and clearly I hadn't actually asked him to do it.
"He said he could give a caution, but on this occasion he chose not to. So, I was actually quite flabbergasted."
Mr Bresland fronted Perth Magistrate's Court yesterday, where he was determined to plead not guilty.
However, the charge had been withdrawn.
WA Police Traffic Operations inspector Vic Hussey told 6PR the incident had been a mistake.
But he said window washers were known to cause a "lot of issues and a lot of problems" and defended the police officer in question, who he claimed had been "trying to solve the problem".
He said it was an offence to pay window washers but "the penalty of $50 suggests how we actually view that as a society".
"So, we had a chat with the officer and he reflected upon what he had done and said, 'Well, look, it probably was an exaggeration and probably wasn't the best way to address the issue at hand'," he told the station.
"The reality is, unfortunately, sometimes you can make a decision and then reflect upon on it, and it's not necessarily the best one.
"Sometimes we get it right and sometimes we don't and on this occasion we stuffed up."
News.com.au approached WA Police and Mr Bresland for comment.
In New Zealand, a law introduced in 2017 forbids window washing with a $150 fine. However, that fine is for the washer, not the driver receiving the service.
