You empiricists often loose the plot when it comes to these sort of matters. A thought experiment: A murder during a fancy dinner party. Victim was shot in the head with a 9mm round. Guest A is very evasive and was in the vicinity where the body was found. Guest A is known to have a 9mm handgun. Guest A quickly destroys his handgun and forensics cannot recover any information from it. Guest A writes a letter explaining that the shot came from outside the house, without any mention of his potential role in the murder, and his friends at the local newspaper not only run the letter, citing him as a expert, but run hit pieces that anyone claiming otherwise is a racist. Reason allows us to know Guest A was involved. In the absence of evidence sometimes reason is all you have. This is one of those cases, no science is required just a little life experience.
