In Toronto, hundreds of supporters of the Tamil Tigers (terrorist group) ran onto one of the busiest highways in downtown Toronto yesterday and completely shut down the highway endangering not only themselves but also the motorists using the highway.

If you look closely at the pics you'll see the red Tamil Tiger flag being waved and in some of the photos you might see placards with the leader of the Tamil Tiger rebel group. The Tamils want part of Sri Lanka to be given to them but the Sri Lanka gov't will not allow it. The Tamil Tigers have been labeled a terrorist organization by the Canadian Government but their protests have been largely tolerated by the government.
Imagine if supporters of Hamas were to block this same highway tomorrow demanding that Israel leave Palestine. Would anyone tolerate that?
