This would have been about ~12 year ago. I saw something very, very similar with my own two eyes off of Fremont St ( was staying at the Golden Nugget). There were live bands, street art, etc. etc. and cops on horseback, they had a guy tethered and walking away from a crowd of people with him.
I understand that this isn't a great look, but only because those that want to see racism everywhere they look will see it here. If the police in the picture are indeed racists looking to belittle the man simply for the color of his skin, I am right there with you all in being appalled. But, I'm not going to invent it because two cops detained someone and used rope so he couldn't get away and a vehicle wasn't available right away. That's just racists creating racism at this point.
