Apart from the fact that the driver is clearly not deaf, you have a point.

The point is that cops are frequently surprised by the deaf ~ or non-deaf folks with headcolds, so they should not always assume they are dealing with someone who heard what they said.

Particularly if they get into that high squeaky voice thing that shows a great deal of adrenalin flowing in their system building up to a major taserburst!

In any case, the taser cannot be considered to be "non lethal".
