They look for candidates for the MK-ULTRA zombie robot program. I suspect every single one of these mass shootings, or most of em, were done by their zombie robots.
Anyone notice that there were no zombie robot shootings during the Trump administration. Look how many there have been since the communist coup. Wonder how much it cost and how long it takes to produce a good working zombie robot? Wonder how many they got all already pre-programmed and just waiting to wound up like a toy and then set loose. All on taxpayer expense, of course.
See my above post.
