This is a felon in possession of a firearm case. The defendant and his wife were involved in an argument. The argument became heated enough that the wife called the police through the 911 system. The tape recording of the telephone call contained the following:

Caller: Would you send a car to 308 Bell?

Dispatch: 308 Bell?

Caller: Yeah, please hurry.

Dispatch: What's the problem?

Caller: He pulled a gun on me.

Dispatch: OK, you stay on the phone, OK?

Caller: I can't. Here he comes.

Before trial the defendant moves to preclude evidence of the telephone call. At the hearing on the motion, the following happens:

Judge: This is defendant's motion to preclude evidence of a 911-telephone call. Defense, what's your argument?

                A. What objection should be made?

                B. What are the best arguments to support the objections

                C. What are the best arguments to oppose the objections?
