I tried to look for an IED fax explosion in Tucson, but came up with this:
When an individual is unable to control aggressive impulses, participates in unprovoked angry and violent behavior, and frequently explodes in verbally aggressive outbursts that are grossly out of proportion to the situation/environment around him or her, it is possible that he or she is suffering from intermittent explosive disorder. Intermittent explosive disorder, also known as IED, can cause people to inadvertently destroy interpersonal relationships, fail in academic or occupational settings, and become isolated and detached from the world around them. Yet, life does not have to be this way because there is help available.
Sonora Behavioral Health, Tucson, AZ
It wasn’t an IED, it was a “suspicious object” that included wires and stuff so they blew it up, and then somebody looked at the pictures (taken before it was destroyed, probably) and said “that’s a fax machine”.
