Around the world in tear gas: Protests stifled in 2014

As a suburb of St. Louis, Missouri, seethes with anger after the murder of an unarmed black teenager over the weekend, images of demonstrations are reminiscent of protest zones across the globe. With security forces lobbing tear gas canisters at people to quell unrest, individuals sometimes simply pick up the devices intended for crowd control and throw them back at the riot police.

The images below show similar circumstances in many different locales where political discourse is expressed in street clashes. From anti-occupation rallies in the West Bank and sectarian protests in Bahrain to anti-government agitation in Ukraine and Venezuela, marchers are often eager to turn law enforcement's own techniques against police.

While such photographs may be familiar in unstable Egypt, perhaps they are more shocking emerging from the Midwest of the U.S.
