This is what collective mobilization looks like.。

High school students across the country walked out of school on Wednesday to protest inaction from politicians on gun control policy. The protests are a direct response to the deadly high school shooting in Parkland, Florida last week that took 17 lives.。

A striking way to see the spread of this movement — from both a macro, and micro perspective — has emerged on Snap Maps.。

By mid-Wednesday afternoon, Snapchat's map surfaced multiple featured and trending stories of walk outs from California to Texas, Florida to D.C., and more states and schools across the country.。

Some survivors from last week's shooting spent Wednesday in a "listening session" about mass shootings with President Trump, Vice President Pence, and other members of the administration. Protests from the Parkland high school students went viral, as student Emma Gonzalez led a chant "calling BS" on excuses for inaction on gun control. The students' calls for action have been subsequently ridiculed and belittled in the conservative commentators on the basis of the age of the activists. There are more marches and walk-outs planned in the coming months to demand action from lawmakers.。

Clearly, the message is catching on. 。
