How  would I react in that situation?
I've not been that drunk in a long long time, but I would hope that I had enough sense to ask him to delete the offending snap, and that would be that.
On the other hand, if I was the type that enjoyed being drunk and puking up on the pavement, I might just be tempted to have a go at a guy with a camera, an easy excuse for another drunken brawl. After all, the no win no fee guys will pick up the legal tabs and she might just have a compo claim to boot.
Closing time in the city centres in this country is becoming a national disgrace, the Polish arts and social science degree guy said he  wanted to show the other side of Edinburgh, (one where the street performers need the councils to shovel up their mess, the police to stop them fighting, and the hospitals to stitch up and care for their stab victims).  Perhaps its wrong to show that side of a city and it should be hushed up and brushed under the carpet?
The "Sherriff" fined him to remind him that chivelry is not dead....What utter utter nonscence, the only one breaking the law appears to me to be the drunken louts who think they can roll about the street puking etc. and be above the law "Coz wur pished man".
With all the terrible things that go on in the world, where is this guys "crime" in the grand scheme of things?
Of course theres a time and a place for everything, as I said before,  I objected to someone taking a picture at a funeral years ago, but to go to the police about it is just plain stupid. Perhaps a right good old vodka binge might change my mind though!
For the record I would not have taken the picture either....I might have nicked her mobile, and rifled her pockets....but not the picture. 
(Perhaps not,  the CCTV cameras  might catch me!)
The photographers biggest regret should be his choice of lawer.
I'm tempted now to go into Glasgow tonight and get arrested for photography, I would not plead guilty, and I would not use Andy Houston from LawersRUS.
