Show us exactly where you mean Zark. It all looks pretty inocuous to me and I can't be arsed with playing conspiracock spot the difference if I'm honest.
In any case I'm hard pressed to see anything on that photo that's particularly out of the ordinary, or unlikely to be able easily explained - these are low resolution CCTV stills after all, with all the artefacts and visual problems inherent in this format. The people talking about bars going 'through' people clearly haven't a fucking clue about the foibles and shortfalls of footage.
To put it another way, even a two-bob Photoshop operator would be able to come up with razor-sharp (and suspiciously so) stills that would outwardly be more convincing than the one we have. No bloke manipulating the image would make such a stupid mistake, particularly with ill-informed numpties waiting to pounce on any inconsistency.
I recommend some of the people on this thread take a course in photoshop and stop speculating over such nonsense.
