He is a veteran who served in Iraq, and received training about the people, the region, the cultural and geographic features, in addition to as much information into who they would be fighting as possible. Perhaps this included pirated training videos of the Iraqi training process. In any case, when someone with a history of mental illness and violent behavior claims that the 'government' is making him watch videos via 'mind control', investigation is unlikely to reveal that 'US Intelligence agencies' actually possess that technology. With two DV's and obvious signs of mental illness, it would have been helpful for this country to support the intelligent regulation of weapons thereby being able to keep his gun based on his recent history, and to offer comprehensive medical help-- to fully support programs to help people with mental illness, before suicide or homicide occur (suicide or being victimized themselves, being by far the more common outcome).
