Protesters across the nation organized walkouts from work and school Monday to protest police brutality and last Monday's decision by a Missouri grand jury not to indict white Ferguson Police Officer Darren Wilson in the August shooting death of unarmed black teenager Michael Brown. The demonstrations, dubbed "Hands Up Walk Out" and #handsupwalkout on social media, are the latest in a series of nationwide protests against law enforcement officers killing black people with impunity, heavy-handed police tactics and more.

The events, planned for more than 30 locations from Stanford University in California to Philadelphia City Hall, will feature students and workers walking out of their schools, houses and places of employment at 1:01 p.m. EST, the time of Brown's death Aug. 9. "Leave your school, office or home with your hands up and gather at the time of Mike Brown's death," read an announcement of the event posted on the Ferguson Response advocacy group's Tumblr account.

Participants are asked to leave the locations with their hands in the air in solidarity with the "Hands Up Don't Shoot" movement, which has seen protesters at demonstrations across the U.S. chant the slogan with raised hands in recent days. The gesture was even endorsed by several members of the St. Louis Rams NFL football team, who put their hands up as they took the field against the Oakland Raiders Sunday.

Some sites will see marches, while others will be limited to gatherings and rallies. The University of Iowa's "Hands Up Walk Out" event, for instance, will feature a march on the school's Pentacrest, according to KGAN-TV, Cedar Rapids, Iowa.

Twitter users sent many tweets Monday in support of #handsupwalkout, and imploring others to take part in the protests:
