Kennedy:
1) Was driving with his headlights off at 2:45 a.m.
2) Swerved into oncoming traffic, almost sideswiped a police cruiser, and crashed into a security barrier.
3) Was observed staggering after he exited his vehicle.
4) Smelled of alcohol.
5) Lied about being "late for a vote".
6) Lied about not having had alcohol,
7) Was seen drinking at one or two bars earlier in the evening.
I'd say that the above facts sufficiently form the basis of a case. I'm sure that the two sergeants who drove him home could provide testimony that would ice the case. No need for any test results.
Let's give Kennedy a pass.
He is, after all, a Kennedy, which means that he is part of America's unimpeachable nobility.
Instead, let's go after the coppers. They don't have the Kennedy impunity.
Let's sic MADD on them.
