Was the bench around a corner or jutting out? Was the boy part of a crowd that obscured the bench? Is the bench somehow camouflaged? Is it static and stationary?
Is the boy fully sighted? Is it dark? Did someone distract him? Was he panicked by someone? Could he have deliberately run into it?
I agree about the latter, he’s a centrist Democrat at best, but he’s got a lot at stake directly opposing the Trump administration on their latest actions as the US slips into dictatorship, and I’d hardly call that cowardice.
