On March 12 2002 the Department of Homeland Security started a system to communicate the threat level of Terrorism with a color codes. Until it got replaced 2011 its state got changed 8 times.
During these 3326 days a total of 4 people fell victim in the US to the actions of Islamic Terrorists. Unless I have overlooked something at this comprehensive list these seem to be
- July 4, 2002 LAX shooting 2 victims
- July 28, 2006 Jewish Federation shooting 1 victim
- June 1, 2009 Recruiting Office shooting 1 victim
Observations with a sample size of 3 are inherently pointless, so it is not worth pointing out, that these 3 incidents fell into the times when the thread level was as its lowest levels.
It is worth to observer that the daily death count from Islamic Terrorism in the USA during this period was 0.0012.
Covid 19 was more than a million times deadlier during most days last week.
