Rosengarten raised the argument that no gunshot remnants from the backpack and live bullets seized at the scene of the incident were examined, and no comparison was made between the remnants of the gunfire from the defendant and the exhibits with the remnants of the gunshot from the cartridge.
In addition, Rosengarten noted that the prosecution's opinion did not distinguish between those who fired, and those who stood next to the shooter or those who touched an object contaminated with gunshot remnants; Hence his conclusion that there is no possibility of linking the defendant to the shooting incident.
It was claimed that no bullet remnants from the bullet found at the scene were examined, and therefore it was impossible to know whether they matched the remains of the bullets found on the defendant and his belongings.
According to Rosengarten, the matching claimed in Dr. Israelson's opinion on behalf of the prosecution is based only on the symbol at the base of the backpack seized at the scene, but ignores the existence of several types of Western ammunition;
In Rosengarten's opinion, contrary to Dr. Israelson's position, according to which one of the 12 remnants of gunfire was found in the shipment bag, which contained Western ammunition, including aluminum, and is suitable to be a "memory of the weapon" from a previous shooting. Rosengarten believes that one of the 12 remnants of gunfire is not suitable to be considered a "memory" of a previous shooting. According to him, the conclusion is that in this exhibit there are remnants of gunfire from several types of ammunition.
It was claimed that the type of gunshot remains from the backpack found at the scene was not examined, and this greatly weakens the connection between the defendant and the shooting incident and emphasizes the failure to examine the remnants of gunfire from the backpack.
Rosengarten stated in his testimony that the remains of the gunfire found on the defendant and his clothes were in tiny quantities, and that no significance should be attributed to these findings, since they did not link the defendant to the shooting incident. Rosengarten also stated that the backpack found at the scene had not been examined and in fact there was no information about the type of ammunition used in the shooting incident, while remnants of gunfire of two types of western and eastern ammunition were found in the shipment bag.
