we have several problems here

1) pornography on a works computer - pornography is a well known vector for malware. There would be records from that time - police notebooks, statements at an inquiry. On any works computer it is a concern, on a government PC it is a security issue. RBS had problems, TK MAX, Uber and a load of outfits who haven't come clean, how did they happen? Who knows? But the weakest link in a computer system is the human, and there are enough of them to fall for phishing in any outfit. It only takes one!

2) integrity of police officers is called into question. Retired police officers are not bound by the same disciplinary code as serving officers. But it does impact the image of the police.

3) There is a cover up, which may be in the interests of the country's security, but see 1). You choose which takes precedence in the long shadow of Russian interference in elections and referenda.

4) the only reason that Labour politicians are not dragged into such an issue is chance.

5) Politicians spend long hours on government business, and marriages suffer as a result. It was proposed 40 years ago by a serving MP that: "there is a case for a Westminster brothel to be set up". Surely there is a case for parliament to provide safe PCs for extra curricular surfing for the same reason.

BTW parliamentary bed hopping is nothing new. I was told by the son of Harold Wilson's solicitor that there was a contractual agreement drawn up for his wife to not pursue divorce over adultery with Marcia Williams. And the Marcia connection has been confirmed since by many who were there at the time.

It's a jungle out there.
