Who would they call? Do you generally keep your cell phone on when you are at a funeral?
In addition, why would you expect anyone from the funeral home to have noticed such a thing? The police have historically protected funeral processions from thuggish jackasses...now they hire them.
In every funeral procession I’ve been in, we’ve been briefed by the funeral home on how to drive, and told to turn our lights on. One funeral home even had magnetic stickers for the cars. And a funeral home car always followed up in the rear, who would have seen a car pulled over.
Of course, in many of our local funerals, the sheriff’s office provides a few cars to help block cross-traffic at lights so the funerals can proceed.
I’ve seen no more information on this story suggesting how they did the funeral procession.
