Thanks to Jamie from Forensic Focus who pointed out my mistake in episode 3. I wrongfully stated that Brian Carrier did PTK and Jamie has corrected me in saying that Dario Forte (founder of DFLabs) is the main man behind it instead.
Sorry for the mistake, I do get confused from time to time and will likely need correcting in the future.
