These “homegrown” terrorist have several things in common. They are highly educated, have their own money resources, have communicated their radicalism on the internet, they are known as radical to their friends, and they are all muslim. Seems to me that is a profile that should be worked.
Also seems that the Muslim community could help by ID’ing those known verbal radicals. If you talk to any University Muslim moderate, he or she will be able to tell you who among the students are “radical” and fundamental. They should be thrown out of the country.
As for who the enemy is, a poll was done last year ...out of 1.6 BILLION Muslim over 25% of them are radicals...do the math and then you try to pinpoint who the enemy is and isn't.... 091101 taught me all I needed to know about Islam. If that makes me a bigot, then I am a bigot.
