I agree that Huckabee did not have churches in mind. Huckabee is notorious for attempting to put more of ‘his’ religion in schools and other government functions. Huckabee insinuated that had God been a larger factor in government schools the acts of violence would not happen. Huckabee chose to ignore the church shootings because it would not be compatible with his God focused agenda to merge the Christian religion with government enforcement powers.

Church shooting over graffiti outrages L.A. neighborhood

The Sunday-evening service e was near an end at the small storefront church on Beverly Boulevard when one of the congregations came upon a commotion outside.
A teenage girl was spray-painting graffiti on the side of the Principe de Paz church in the Westlake district. When the man asked her to stop, she knocked him to the ground and continued tagging. Two other parishioners then came outside. A man emerged from a car parked next to the church and opened fire, killing one churchgoer and wounding the other.
Hearing the gunshots, churchgoers poured out into the street and knelt beside the victims, praying in Spanish, according to witnesses who watched the scene in disbelief.
“For God’s sake, if people going to church aren’t protected, then who is?” asked a nearby business owner, who bolted out of his store when he heard the gunfire and saw the dead man lying on the asphalt, surrounded by loudly grieving parishioners.
