How it differentiate
The fundamental difference between the perpetrator of a crime and an innocent person is that the perpetrator, having committed the crime, has the details of the crime stored in his memory, and the innocent suspect does not.
P300 or MERMER i.e. Memory and Encoding Related Multifaceted Electroencephalographic Response is emitted from an individual’s brain beginning approximately 300 milliseconds after it is confronted with a stimulus of special significance.

It does not detect how that information got there. .
Brain fingerprinting detects only information..
Where the suspect knows everything that the investigators can ask..
