Only in a fascistic police-state does one have to produce ID when some "authority" says: "Papers." The article suggests the Soviet Union in the 1950's, but I think of the hundreds of anti-Nazi movies produced in the US and UK and Canada before, during, and after WWII.
If you don't have reasonable grounds to suspect someone of having committed, or about to commit, an actual crime, you don't have legal grounds to arrest that person for not showing ID. Even having to carry ID is highly questionable in a free society. It doesn't matter that it's during a window when the G-8 or G-20 or anyone else is meeting anywhere. There was no emergency that could possibly justify overriding human and civil rights.
Canada, Ontario, Toronto, and all the G-20 members are shameful. Yes, violent anarchists are idiots for damaging property, but that doesn't mean you take away the rights of the innocent. There are also agents provocateurs about for sure.
The very actions of the police-state are proof that the demonstrators and protesters have completely valid reasons for protesting and for demanding a redress of their grievances against the plutocratic/kleptocratic state.
