To put this in perspective, before the tin hats come out, from the same source:
That was the assessment of a terrorism advisory organization inside the U.S. Army called the Asymmetric Warfare Group in 2011, acquired by Danger Room. Its concern about the warning signs of internal radicalization reflects how urgent the Army considers that threat after Maj. Nidal Malik Hasan shot and killed 13 people at Ford Hood in 2009.
And from the top of the chart itself:
There is no way to be 100% certain that an individual is becoming radicalized to the point that they may be considering violent action. However, recent experiences show that there are certain warning signs, or early indicators, worth review. The information below is a general guide for military personnel and leaders at every level to give the user a basic understanding of when further action might be warranted. This guide requires the user to understand the fine line between the protection of ones rights to privacy and the need to protect others. It should be used in the same judicious manner one uses a chart with indicators of suicide. The graphic on the left shows possible indicators of radicalization from the inception of the thought increasing up to the level of violent action. The indicator decision chart on the right outlines a step-by-step process for identifying, evaluating, and responding to possible indicators at each level.
Patriotism is not waving a flag, it is living the ideals
