IMHO, there is little doubt that these were three Islamic Terror attacks.
I would normally say that they were probably individual acts of Sudden Juhad Terror Syndrome. (Which I kept track of from 2002-2009 here: http://www.jeffhead.com/sjs/)
But since they all occurred within a few hours of one another...I have doubts. It could well have been orchestrated, all three by one group or set of people. Particularly that they believe some of the bombs in to different locations were made by the same people.
Hibernating Hillary was the “tell” on this. When they injected her out of her deep sleep for the interview last night, within the very first few words she sputtered was the statement that she had been briefed on the bombings (which she shortly after scolded Trump for using that word) in NY and NJ, and the incident at the Mall in Minnesota. Why would she had been “briefed” on the mall deal if not known right away it was rag-head motivated?
