Here's video of how our good Sunni ally, Bahrain, Kingdom of, embraces peaceful protest. The pro-democracy group, armed only with placards, marched on Bahraini armoured vehicles in their path
This allows you a bit of perspective of how the protest would have been seen by Bahraini/Saudi soldiers manning their heavy automatic weapons from their armoured vehicles. About halfway through the clip is the scene where, after the killings, the protesters return and sit down right in front of those same armoured vehicles.
Oh well, I suppose Canada should really keep its nose out of this. It wouldn't do for an emerging fossil fuel superpower to criticize another rancid petro-state.
