there's a recent article reporting on the NBC package he sent.
news.yahoo.com...
in the report there is an interesting sentence by Cho
... to inspire generations of the weak and defenseless people."
now, to my perspective,
they (the weak & defenseless) are the
'Brothers and Sisters' you quoted him as saying, and theorizing
he must mean the Jihadists or Islamics as 'Brothers and Sisters'....
also, in my perspective, the "Ismail" may be more the detached
Ismail narriator of the Moby-Dick tale of perdition & assassination,
he donned that personality and also acted out the role of Ahab in
slaying the great white leviathon/beast
Cho could do both, because he was schizo.
hence the inked but aborted identification which might have read 'Ismail Ahab' but instead he 'X'd after the 'A'...because of his inner
conflict
with his 'Christ' identification as a slain prophet/messenger/icon
never mind the last parts...
but give consideration on the 'brothers & sisters' = 'weak & defenseless'
rather than bringing in Muslims or Jihadists as bro's & sis's
