I think most facts point to two very confused and deluded youngsters, it's a joke even calling them "terrorists" or "Jihadists". Their madness adopted an Islamic tinge because of their roots, but IMO they're not very different from all the other disturbed American young people who commit gun violence.
I think you're wrong here. The vast, vast majority of gun violence is directed against specific targets. And for the remainder who start randomly shooting people, they seem concerned with notoriety and don't make any attempt to conceal their identity or get away with it.
I figure this probably began with the domestic violence conviction that derailed the older brother's plans for his life in the US. If you come from a society where a given behavior is considered normal and you move to a new society which think that not only is that behavior wrong but that it makes you an intrinsically bad person, well, that's a hard pill to take. More so in that to accept that this is so bad you now have to accept that everyone you knew and respected back home are then bad people.
Or you could just listen to those who say that you and your people are fine, it's just America that's corrupt and decadent. And here's a template for acting in a way that'll make you the hero, rather than someone who blew his chance.
Completely agree, that is what I was kind of trying to say. The evidence points to two very angry and confused young men and there may have been a slight influence of fundamental Islam. I wouldn't be surprised it this influence was self imposed through YouTube and such though.
