Apparently it is an AP invention—in an article titled “Allahu Akbar” Gunman Not An Arab, But A Black Guy Who Hates Whites, about a Disgruntled Minority shooting in Fresno, I noted an AP Tweet that said "Fresno police say suspect in triple slaying told them he hates white people, shouted "God is great" before killings.

Update: “‘Allahu akbar’ doesn’t mean what media says it means.” according to Robert Spencer. He says that it means “Allah is greater,” meaning Allah Is Greater Than Your God or Government." Islam is not a religion of peace, and it doesn't do ecumenism.
