I cannot completely fault the cops. I know it's not the method you're
accustomed to in the UK, but this isn't the UK. There are many instances
where idiots get out of their vehicle and kill a cop. They cannot know
or assume the type of person they are dealing with. EVERY driver should
know how to act when/if being pulled over by police. Stop the car, turn
off ignition, role down window, hands on wheel and await instructions.
Being deaf does not excuse that. It is the responsibility of the deaf
driver to have a method of communication, such as paper and pen/pencil,
sign, etc. to notify if pulled over. In some states, the handicap is
noted on the license.
Lights on a police car are their for a reason. There is no excuse to not
see them and continue driving. This guy did, finally stopped and exited
the vehicle waving hands. The cops had no idea of his intent. If he
would have stopped sooner, remained in his car, he'd be alive. Don't try
to pin this on gun happy cops.
