No one should judge the parents of this kid. From the father's description, the young man was not unlike many young adults in their late teens: disillusioned, no idea of a career, sick of school, wanting independence yet no way to gain it, weak. In other words, a typical product of the drug and filth infested public school system. The kid may have been a willing subject into an CIA run Islamic tainted manchurian candidate sect, speculation I know, but entirely possible in this wicked day. Much of what we know about delta subjects comes from old released research spoon fed to us by the government, but it continues today, only on a more sophisticated basis. The shoe bomber, underwear bomber, Boston marathon, Oklahoma City, the Colorado school shooting... Some idiots are meant to fail to be scape goats and draw attention to the crazyiness of it all and point the blame to poor parenting, but its quite possible another story entirely.
