Carter Jr. said in a statement the agency was "outraged by this senseless act of violence.""Such attacks are not only unacceptable, they are also a felony," Carter wrote. "We will utilize all the resources at our disposal to find the perpetrators and hold them accountable to the fullest extent of the law.
