Sampson, 32, shared several videos on Instagram on Saturday from a protest in Los Angeles, where he was shot by officers multiple times by rubber bullets, as well as hit with batons.
In one of the videos, Sampson revealed that he'd been shot four times while a later video of the day's news coverage contained a shot of Sampson being hit by an officer with a baton.
After details of his injuries had gotten out, the actor took to Twitter to discuss his experience, revealing he'd been shot three more times.
I actually got hit 7 times with rubber bullets and many with batons.
