No!
Citizens are also not allowed to put other citizens at risk. This is not a case of a toll booth operator failing to stop a drunk. This guy took the drunk to his car so that he could drive.
One has no duty to stop a bank robber. If, however, you give a ride to a bank robber assisting in his getaway, knowing he is a bank robber, you are guilty as an accessory. The key element here is that Powell knew the an was intoxicated.

Get the ducks in a row. The first key element was that the police gave a drunk the keys to his car and sent him on his way with a friend. The second key element is that the drunk drove and got in an accident and killed people. The third key element is that the police incorporated Powell into their own on-the-job negligence. The fourth key element is Powell Powell didn't forced the Pangle to drive -- Pangle freely chose to drive while he was drunk.

Driving the getaway car in a bank robbery is a crime. Giving a person a ride to their car is not a crime.
That said, I bet Powell in hindsight dearly wishes he would have kidnapped Pangle to keep him from driving and been happy to deal with possibility of facing kidnapping charges knowing his best friend was still alive.
