In the US, security staff at libraries are videoed repeatedly tasering a recalcitrant student.
This Youtube video of someone getting evicted from a university library in the UK shows there is still a huge difference - that this is one of the most viewed youtube footages according the university facebook account shows just how little scurrilous footage there is.
Security overstepping their authority? Nope.
Security overzealously enforcing their authority? Nope.
Security halfheartedly lugging some loon out of the library because he was bothering the students and refused to leave when asked politely? Check.
They don't even drop him - they gently lower him to the ground. Well, I suppose it was a little damp, this is in November after all.
The video is only remotely entertaining at the end, when you realise why the individual that the security staff have had to carry out through the doors with a distinct air of boredom was deservedly evicted. As they stand around, looking distinctly uninterested by the tedium of the whole affair, the evicted individual demonstrates that he appeared to believe that his right to free speech included ranting about 'Jaysus' to students who'd rather get on with their studying (although not having a library card means they were clearly legally entitled to ask him to leave).
Apart from making you realise what a thankless task security at a university have sometimes, the general indifference of the student body to this fundamentalist loon has to be applauded...
