Methinks it might be a good idea to either have a “Deaf Driver” sign on their cars or some notation attached to the Driver’s License, License Plate or VIN.
It doesn’t excuse the driver if he was acting a fool, but it should reduce misinterpretations on the part of the cops.
The dead guy had issues apparently. Previous arrests, etc. This isn’t a cut and dry one for the cop haters, IMO.
