Well, if you can't figure it out then 4:20 let me translate. The terrorist was born in the United States. He chose mass murder just like Timothy McVeigh, Robert Dear, Eric Rudolph and other religiously motivated terrorists. By stating a fact--that the terrorists were not immigrants but persons born in the US no one is blaming anything on this country but rather pointing out the futility of blaming immigrants and U.S. immigration policy for acts committed by non-immigrants.
