Google this: DARPA COMPASS. It’s the first entry. This started a while back. The confluence of information replacing the census citizenship question goes a long way to making this happen for those of whatever status in these USA. Algorithms of gaming theory and the OODA Loop can sort out who needs targeting. This seems to be the obvious reference of Trump’s reaction to the El Paso and Dayton shootings on Monday August 5, what his quick due process means. The psych lockup is a dumbed down version. The program usually just gives a target-name to a field operator who terminates the possible terroristic threat. The mere psych lockup for those in these USA makes the program seem a bit more acceptable as a way to do something about mass shootings.
