How could the cop tell she was drunk in the driveway unless he observed her intoxicated before she got in the vehicle?
If she was such a danger to the public, you'd think he would have intervened before then?
Common sense.
A drunk person minding their business in their yard is one thing, that same person gets behind the wheel, even in their own driveway is another. This post sums up why cops are screwed, damned if they do and damned if they don’t.
That post points out that officer discretion is a valuable tool.
