The protest was sponsored by Black Lives Matter, BLD PWR and local rapper YG, and was attended by people of various races and ages.

Widespread demonstrations came after the May 25 death of George Floyd in Minneapolis, who died shortly after an officer held his knee on Floyd’s neck for 8 minutes and 46 seconds.

Marchers in Hollywood were still moving as of 7 p.m. and most appeared to be wearing face masks, although they were still standing closely together. Police presence was low in the area, so some people volunteered to direct traffic as others marched, chanted and handed out water to the protesters braving the heat.

The group was considerably smaller after 10 p.m. as some demonstrators gathered around a makeshift memorial.
