There was an abundant amount of blood, however; most of it was not usable because of a variety of errors due to the police on scene. There was a sock that was recovered from O.J Simpson room that had blood that matched
Ms.Brown's blood, however; it wasn't discovered until a later date. There were times when blood was taken, but was forgotten and lost without a trace. When police detectives took blood from O.J it wasn't stored properly but carried in a detective's pocket for a number of hours. Also, they took a blanket from Ms. Browns house and placed over her body without taking the proper precautions of preserving the crime scene Finally, 15 mL of O.J blood went missing and some people suspected that a known detective by the name of Mark Fuhrman who is a known racist.
I've always believed that O.J was guilty, however; if I was on the jury I would've agreed with everyone else about not convicting him. The reason I would not convict him is because of the Bodily fluid evidence was not properly collected, and i would have to disregard that while considering the type of evidence against him.
