The skytrain was running all night. It stopped bringing people into downtown but was taking people out all night. The picture was taken at 10:30, really late in the riot. Anyone still on the streets downtown at that time, hours after the game ended and hours after the rioting had started, was there because they wanted to be there so it's ridiculous for them to be acting as if they had a right to be there and had a right to reason with riot police and not get pushed out of the way with the thousands of other dickheads ignoring the police warnings.
The police couldn't get at the vandals and goons because of the thousand of idiots blocking the way, standing there with their cell phones encouraging the destruction by being an audience for it all.
They weren't breaking windows or looting (that we know of) but they sure weren't just a sweet little couple caught in a bad situation that the mean police brutalized and overreacted to.
I still think it's a beautiful photo, on it's own but the backstory and the couple's comments to the media, not so much.
