drunk driving

Hello group,
Please forgive a tad off topic but relevant to all car lovers.
Everyone has heard the stories about the drunk driver killing others
and walking away unhurt.
I would simply like to know if that is really true. I've worked in an
emergency room and I've seen plenty of drunks injured and dead.My
small sampling is inconclusive. One can't go by the newspapers either
for the same reason thousands of planes land safely every day and you
only read about the few times a year one crashes.
I've been searching all over the internet for days now for statistics
and there is certainly plenty of data available but I've found nothing
to sup****t or refute that one particular fact. I'd appreciate any
suggestion of where to look next.
Im****tant - I'm just looking for the facts here, please do not misread
this as some kind of rationalization for drunk driving.
