In some cases , once it was learned that a car involved in the accident had ABS brakes , it was automatically assumed that there were no skid marks ; and therefore no search for marks was conducted ! In general , a full skid with locked ...

Accident analysis is not like a classroom problem where the equations are selected and solved, and the matter is considered closed. In this line of forensics, engineering skill must be combined with skillful practice for the successful presentation of evidence to a jury. In this book, the author demonstrates the application of engineering skills, methods, and judgment for analyzing vehicular accidents. A definition of vehicular accident reconstruction and its role in the legal system is provided. General accident statistics are cited, and some general strategies for accident reconstruction are given, along with many examples and case studies. The author includes novel and unusual treatment of the momentum method and coefficient of restitution (which is not yet widespread in accident analysis) and shows how to select the best methods of analysis in a given accident reconstruction.
The investigator must be careful to check that the yaw marks have not turned into a sideways skid of the entire vehicle. This can be observed by measuring the width of the mark. Tire patch size almost doubles as the tire slides sideways ...

Judgement at Stoney Creek has been released in a new edition of an aboriginal studies classic: an engrossing look at the investigation into the hit-and-run death of Coreen Thomas, a young Native woman in her ninth month of pregnancy, at the wheels of a car driven by a young white man in central BC. The resulting inquest into what might have been just another small-town tragedy turned into an inquiry of racial tensions, both implicit and explicit, that surfaced not only on country backroads but in the courtroom as well, revealing a dual system of justice that treated whites and aboriginals differently. First published in 1990, Judgement at Stoney Creek has been hailed for its moving and deeply personal depiction of a controversial subject that continues to make news today--how the justice system has failed Canada's aboriginal people. This new edition includes a new preface by the author, who returns to the area to discover how much racial relations, and the relationship between Natives and the justice system, have changed.
