For What It’s Worth typically turns up in such revisionist historical accounts but it has nothing to do with integration, assassinations, or the Vietnam war.

The Sunset Strip curfew riots, also known as the “hippie riots”, were a series of early counterculture-era clashes that took place between police and young people on the Sunset Strip in Hollywood, California in 1966.
...annoyed residents and business owners in the district had encouraged the passage of strict (10:00 p.m.) curfew and loitering laws to reduce the traffic congestion resulting from crowds of young club patrons.[3] This was perceived by young, local rock music fans as an infringement on their civil rights, and for weeks tensions and protests swelled. On Saturday, November 12, 1966, fliers were distributed along the Strip inviting people to demonstrate later that day. Hours before the protest one of L.A.’s rock ‘n’ roll radio stations announced there would be a rally at Pandora’s Box, a club facing forced closure and demolition at the corner of Sunset Boulevard and Crescent Heights, and cautioned people to tread carefully.[4] That evening, as many as a 1,000 youthful demonstrators, including such celebrities as Jack Nicholson and Peter Fonda (who was handcuffed by police), erupted in protest against the perceived repressive enforcement of these recently invoked curfew laws.
...”For What It’s Worth” performed by Buffalo Springfield and written by Stephen Stills. The song is often used as an antiwar protest song despite not being originally intended as one.[9]Regarding the events, Stills has said: “Riot is a ridiculous name, it was a funeral for Pandora’s Box. But it looked like a revolution.”
When “For What It’s Worth” came out late in 1966, I liked it. The Sunset Strip riots were in the news at the time, but I didn’t associate them with the song, which I thought to have been inspired by the mass rallies and demonstrations that were part of Red China’s “Great Proletarian Cultural Revolution,” which began earlier in the year.
