Last week, leaders of nations from both the G8 and G20 gathered in Ontario Canada, for meetings in in Huntsville and Toronto. Canadian authorities planning for the event spent an estimated $1 billion, mostly for security. Tens of thousands of protesters descended on Toronto, looking to have their voices heard on a broad range of issues, from indigenous rights to anti-capitalist ideals, to human and animal rights, and much more. Many peaceful marches took place throughout the weekend, but on Saturday, a small group of "black bloc" anarchists became violent, smashing storefronts and burning several police vehicles. Harsher tactics and more arrests by the 20,000 police officers deployed to Toronto soon followed, although many of those arrested were released from a temporary G20 detainment center soon after.
