"Organizers say extremists have posted calls for violence on Facebook and YouTube. Those include messages such as: 'Blood will flow, but there will be no gay parade,' or 'Oct. 10, day of shame.' Gay groups demanded Friday that police detain those responsible for the threats. They said police have done little to punish those who made threats last year."
Last year, despite anti-gay graffiti all over Belgrade warning gays to stay away, police said they would protect marchers, but got cold feet at the last minute and said the parade was canceled.
