It’s protocol for any high profile perp walk. It’s how things have been done for a long time.
No it’s not. There are so many comparable pictures out there today. You can just look at them next to each other.
I’d urge you to look up a guy named Timothy McVeigh. There’s tons of images of the army of police officers walking him. And it goes all the way back to Lee Harvey Oswald. Remember that guy? TONS of cops around him.
Think they were afraid?
Also, I’d urge you to read this, as it explains how exactly the purpose for the perp walk.
Trust me- no one is afraid.
