“Are emergency vehicles now going to eliminate sirens and klaxons because they are no longer necessary?”
Please!! He was deaf NOT blind! Could he not see the blue light special in his rear view mirror? Now if the cop was not flashing that I’d see there was a problem OR if it was one of those undercover models that did not have the blue lights on top (as they should! I’m against the undercover ones pulling you over) then yes...he may not have seen the blue lights flashing because he did not hear the sirens.
Just speculating, but I think his deafness, while a contributing factor, had less to do with this final altercation with the police than his emotional state. It sounds to me like he was an emotionally challenged person (perhaps brought on by his hearing impairment).
He had prior incidents with law enforcement. Strike one. Did being deaf/being emotionally challenged have anything to do with that? Maybe. May have contributed to both cars getting damaged. Was he trying to get home so someone could assist with communication? Perhaps. Adrenaline was likely a factor by that time.
Getting out of the car at the final destination instead of keeping his hands at 10:00/2:00 (sign language notwithstanding)? Yep, to a LEO, big no-no. I’ve been involved with LEOs, and you keep you hands on the steering wheel. Maybe he didn’t know any better - sad if so.
At any rate, I hope an investigation yields a satisfactory result. JMHO.
