I presume they meant ones who have committed crimes, rather than ones who roughly fit a profile of who might commit homicide.

I agree that profiling someone like this could lead into some serious Minority Report territory where you try to arrest someone "before they commit a crime", which will inevitably sweep up a lot of people who wouldn't have committed such a crime.

Having such a deficit in empathy could be considered a disability, like many others, although not one the individual would necessarily be able to recognise, because to them, an absence of empathy would be "normal".
