ASSIGNMENT

Watch my video for the theory behind spatter (and the etymology), and take a look at the YouTube video to see drops on various surfaces.  I have also included three videos taken from Court TV that show a blood analysis expert, Dr. Lee, testifying at the OJ Simpson trial in 1994.  This gives a good perspective on how blood evidence is given in court.
