I'm not sure Chope objects to protecting women and dogs from disgusting or violent behaviour. I think the argument (aside from his apparently standard objection to Private Members' Bills, which is a separate issue) is that making something illegal or increasing the potential punishment for behaviour like upskirting or stabbing a police dog, which seems to be what the proposed legislation in England is about (upskirting is already a crime in Scotland), does not technically "protect" women or police dogs. It (potentially) punishes perpetrators.
Proper consequences for disgusting or violent behaviour are good but they are not "protection". Bullet- or slash-proof dog jackets would be protection and not wearing skimpy skirts would do more to protect women from upskirting. Please note, I am not saying that women shouldn't wear skimpy skirts if they want to, nor disapproving of the practice, just pointing out that certain other types of clothing that are just as fashionable and stylish give a woman more "protection" from upskirting. This is true whether one likes it or not.
The proposed laws on both these topics are about punishment for offenders, not about protection of women or dogs, which is what is claimed in this quote from the Guardian: The criminalisation of upskirting … is a welcome first step towards a more comprehensive law protecting victims of all forms of image-based sexual abuse, which also includes so-called ‘revenge porn'
I think everyone, even Chope, and even probably upskirters and police dog attackers, know already that such behaviour is totally unacceptable.
So, just to be clear, I'm not arguing against greater punishment for convicted perpetrators of upskirting or attacks on police dogs. I'm arguing against calling laws to increase the consequences of such behaviour "protection". So I think, like most other people, it seems, that Chope was probably wrong to oppose the PMBs on these topics.
The government could change the law on how to stop PMBs too.
