Being a weak kneed Christian patsy does not seem to be right behavior when facing a threat. In this case, there were clues as to his intent and purpose..... Hiding his identity.... hidden hands.... refusal to dialogue...etc....and when the guy gave the Islamic greeting and Islamic gesture, the path forward was clear.
The greeting phrase he used is not exclusive to islam. I have heard the same greeting from Christians who come from the region of the Arabian peninsula, of which there are a fair number around.
That said, I have also known some nutjobs who assume middle eastern names and phrases in an apparent attempt to gain religious authority or maybe they just crave attention.
