A communist agitator violating US law against individuals gets hurt. The press focuses on the grief of the parents, but ignores the reality.
Tristan Anderson violated US law prohibiting private citizens from conducting their own foreign policy. He was not elected to conduct foreign policy, nor appointed to a governmental authority.
His injuries were the product of his stupidity.
The use of the word "activist" in the case of a globe trotting law violating nut does not tell the story. Who is paying for these trips to Iraq, Israel and elsewhere? How does this fool support himself?
