My daughter had an incident like that - an obvious drunk driver with a small child loose in the car - driving all over the highway (4-lane at 65 MPH, no less). She called 911 and told the operator what was happening, and his reply to her was, "Well, what do you want me to do about it?" He then went on to tell her that if the police pulled him over, she'd have to testify against him, and did she really want to do that.... How's that for stupid? To the best of her knowledge, nobody made an effort to even find him to check him out.
