The violence drew sharp words from Republican Gov. Jan Brewer, a vocal foe of President Barack Obama’s administration on immigration. She said it should lead to anger over “the federal failure and political stalemate that has left our border unsecured and our Border Patrol in harm’s way.”

FBI officials said a preliminary investigation showed that Border Agent Nicholas J. Ivie died in a “friendly fire” shooting that only involved the agents.

A .223 Bushmaster rifle, seized on Wednesday, was “recovered in Mexico in the vicinity where Border Patrol agent was murdered,” according to one of the documents. It says the weapon was purchased in the United States but does not specify where.

Maybe Governor Brewer might spare a few “sharp words” about whoever bought the Bushmaster.
