Questioning the Ethics Here

I was reading some news and came across this story:

AMSTERDAM, Netherlands – When Dutch police stopped a car for a
broken headlight and noticed the driver was accompanied by a
prostitute, they gave him a break — and let him pay the traffic fine in
cash rather than sending the ticket to his home.


      

The officer wrote the man a ticket for the headlight and said it would arrive in an official police envelope.

The man "wanted to pay immediately because otherwise his wife could
have seen that he was ticketed on the Europalaan (a well known pickup
strip) in Utrecht, with all the consequences that would bring," the statement said.

After the man begged for mercy, the officer relented and took him to a nearby station to pay cash, it said.

It brings me to question just why the police were protecting this adulterer. He didn't want his wife to know he was ticketed where there are lots of hookers? Why not simply not commit adultery instead of begging others to cover up for you? Not just any others, but the police, who were merely doing their jobs. They shouldn't discriminate like this and protect this cad. He should have been treated like anyone else who had a broken light would have been, not given a pass for his behavior. Apparently, even though street prostitution is illegal in the country, he wasn't even ticketed for that, and neither was she.
