When asked whether he agrees that 90% of the remnants of gunfire fall from the body within an hour after the shooting incident, he replied that on the subject of gunshot remnants there is a great deal of variation between many articles and that heavy gunshot remnants fall after a shooting incident and it depends on where they are, so no one can determine with certainty the percentage of casualties. Rosengarten confirmed that mechanical actions performed by the shooter after the shooting, such as clapping his hands, rubbing his hands or washing his hands, reduce the remnants of the gunshot in his hands. As for objects, since bullet remains are metal a few microns in size, they will stay in clothing fibers longer than on a helmet (p. 639 of Pruitt).
Rosengarten said that as a rule, most of the remnants of the shooting do not pass through secondary transfer, and that there is variation in the attribution of transfer rates between the existing articles in the field. When asked what the rate of transmission in the mainstream is, he answered about 25% (p. 640 of Pruth).
Rosengarten said that one of the 12 particles of gunshot remnants cannot be a remnant of the "memory of the weapon" that belongs to the shooting in another incident, since it is a remnant of gunfire that accounts for 8% of the other particles. When asked what he relied on in his determination, he replied that it was from his own experience (p. 642 of Prut). Rosengarten said that based on the data from the work bag, various mixtures of ammunition were found in the shipment bag and that the shipment bag may have contained other weapons. According to him, since the type of ammunition used in the shooting incident had not been examined, the remains of the shooting could not be attributed to the particular shooting incident (p. 647 of the shooting).
Rosengarten said that ammunition produced in Israel includes two types, one of which contains aluminum. According to him, the prosecution's expert cannot rely on a series of Israeli ammunition production SEARCH and to assume that it has or does not contain aluminum (pp. 662-663 of the protégé).
