Your comments apply in the absence of objective first person witnesses.  If force was used in an attempt to put the woman in the truck and this was seen by objective third party witnesses then evidence exists if for nothing else then disturbing the peace or some other charge.  On the other hand, if the ADA was overreaching with a an attempted kidnapping charge when there were only some words exchanged, it all makes sense.  After all the man was black and we know how the system treats black men if given a chance.
