Thus, the potential for wrongly identifying a dog may result in a dog being held within kennels for long periods or a breed/type being overrepresented in incident reports.44 BSLs do not address the fact that a dog of any breed can become dangerous when bred or trained to be aggressive.14 A change in the current regulations would prevent dogs that are not dangerous but may belong to a specific breed/type from spending long periods in kennels.44 An alternative to BSL is to regulate individual dogs and owners on the basis of their behavior.14 Most of the responsibility for such attacks lies with the dog owner.7 In terms of some legislatures, a person who keeps or controls an animal in his own interest is liable without fault because he/she creates an increased risk of harm to the community.8 Generic nonbreed-specific dangerous dog laws can be enacted that place primary responsibility for a dogs behavior on the owner, regardless of the dogs breed. 3.Why was the irregular shape to the sternum of the two victims significant in the case.

Dog bite marks usually are distorted, and the lack of quality to individualize features can lead to over interpretations of marks.8 Only when deformations are minimal, testing the match using affine transformations can be obtained by importing pictures of both suspected dogs teeth and the bite mark into the open software GeoGebra as reported by Stols and Bernitz.33 Small amounts of warping, shrinkage, and distortion will not modify the relationships of characteristics within a bite mark.33 However, the distortions in dog bite marks are usually nonuniform and beyond the resolution power of affine transformations because of the deep stabbing of the canines and the only superficial penetration originated by the incisors.

This may result in the consumption of gunshot wounds (with or without projectiles) and stab wounds, making postmortem assessment of lethal wounds difficult.10,23,26,34 To make the picture even more complex, in certain fatal dog attacks, injuries may be sustained that resemble postmortem depredation: decapitation and defleshing of the face and head of children by animals occurring during life are often witnessed and are usually associated with significant hemorrhage.4,34 Although postmortem injuries caused by animals do not show a vital reaction and tend to have yellow-reddened, dried limits, trauma to congested dependent areas may show considerable hemorrhage from postmortem oozing.10, We concur with the literature in that histopathological diagnoses serve to reconstruct the event and provide additional information helpful in the overall evaluation in such cases.16,23,35 Koszyca et al34 demonstrated the value of taking tissues damaged by animal bites during autopsy for histological assessment, as this may be a crucial step in determining the timing of the injuries, and in helping to elucidate the chronology of the fatal event.
