I'd like to look at this from a different angle.
Is it not a damning report on the state of our industry (ground handling) that an accident can not be reported for fear of losing one's job? If it was a genuine accident then why should they have fear in reporting such an incident? Accidents happen and we should look into the causes to prevent them in the future. If it was carelessness on the part of the operator then appropriate action SHOULD be taken but if this was a simple accident then I have issue with this. An arrest only makes people even LESS likely to report incidents in the future.
