Is crime scene evidence inadmissible if:
A person is allegedly a victim of a shooting at night. This person calls the police saying that they heard multiple shots (approximately 20) and the police arrive and take a statement. However, the crime scene is not assessed/no evidence collected at the time the police arrive and they tell the victim to call the crime scene unit if they 'find' any shell casings from the shooting the next day but, the police who arrived do not look for the evidence of a shooting when they arrive on the scene initially. The victim waits 2 days and then calls the crime scene unit and produces 9 shell casings that were supposedly apart of this shooting that happened 2 days prior. The casings are from 2 different types of guns. 1 from an M-1 semi-automatic weapon and 8 from a 9mm handgun. If a weapon shoots several times, why would there only be 1 bullet produced? Is this admissible? If yes, then how so? Doesn't it allow the victim to create something that probably wasn't there in the first place? Can we ensure that the crime scene people, who arrived 2 days later, are at our trial?
