Given the definitions already listed, the deceased victim and his gunshot wounds, the revolver, the bullet strike, and expended cartridges are all probative because they are the clearest evidence that a probable crime has occurred that resulted in death.
For purposes of this discussion, I classify and define evidence categories as follows: probative, investigative, and other. The proper evaluation of evidence helps us to determine its degree of importance. Any item of evidence is technically of value, but I submit that it is not inappropriate to assign a degree of importance to a given item that determines how critical it is to a case, based upon the known facts of the case and any subsequent facts that come to light during the active investigation.
This is beginning to look like a “hope for the best” approach. A counterargument may be that we do not want to miss anything, I contend that if we take the time, at the scene, to evaluate the evidence with appropriate criteria, we will actually save time over the course of the investigation, recover all relevant evidence by exhibiting a quality investigation, and demonstrate superior professionalism. We can look the defense and the jury straight in the eyes and list out the rational and logical reasons why we did not collect something or disregard something.
