Locard’s exchange. Everyone thinks DNA evidence is the holy grail of innocence or guilt. But it is just another piece of evidence and must be treated that way.

Awhile back I read an article about some bum who was accused of a murder, based on him having the DNA of the murder victim on his clothing.
It turns out that earlier in the day paramedics had treated the real murderer. And the paramedics had gotten some of the murderer’s DNA on them.
Then later in the day those paramedics treated the bum. Some of the murderer’s DNA got transferred from the paramedics to the bum.
Fortunately for the bum, a clever detective was able to sort this all out.

Amen. And people are getting so brainwashed that they believe the ABSENCE of DNA is proof of innocence.
