It clearly doesn't, as it's not currently a criminal offence
Well, a bloke I used to work with was prosecuted for taking pictures up a lasses skirt in Meadowhall. I was in the pub on a Tuesday evening and I saw him on the telly! It was on one of those fly on the wall documentaries that were popular in the late '90s and early 2000s.
He was charged with a public order offence. Not only that, but I'm pretty sure he was dating a copper at the time too.
