Law enforcement agencies are using tear gas against people protesting police brutality and racism at levels not seen since periods of unrest in the 1960s and 70s, experts say.

We examined how and where it was used. This is what we found. https://nyti.ms/37B2oFO 
Tear gas is banned in war by international law, but it's used around the world.

In the U.S., we found that 98 law enforcement agencies have used it against protesters since demonstrations began on May 26. https://nyti.ms/37B2oFO 
Tear gas has been used across the U.S., from Fargo, North Dakota, to Lakeland, Florida, and dozens of cities in between.

Lawmakers are now pushing back on the extensive use of tear gas. Some cities, including Denver, Seattle, Portland and Dallas, have all temporarily banned it.
Tear gas is meant to drive people to flee the gas. But protocol calls for there to be an escape route, unlike this case from Philadelphia, where police officers threw tear gas into a large crowd trapped on the side of the highway. http://nyti.ms/37B2oFO 
Misuse of tear gas can cause debilitating injuries, like permanent vision damage, asthma and other long-term injuries.

A 21-year-old student protesting in Fort Wayne, Indiana, lost an eye after being hit by a tear gas canister. http://nyti.ms/37B2oFO 
Police chiefs across the U.S. defend using tear gas, saying that it's a last resort after ordering crowds to disperse or in cases where officers were faced with violent protesters. In some cases though, videos show tear gas was used on peaceful protesters. http://nyti.ms/37B2oFO 
Tear gas is indiscriminate, so it makes it hard for the police to limit the impact to the intended target.
