front door, knocked very loudly and identified themselves and their purpose as required by A.R.S. § 13-3916. Officer Yanez heard the officers knock and announce, but he could not see them. Appellants did not say anything and after about ten seconds the officers at the front door knocked again. Appellants still did not say anything. After getting no response, the officers asked and received permission from their on-the-scene supervisor to break in and they did so.
Officer Yanez did not know appellants were the only ones in the house and drew his weapon in order to protect the officers going to the door. Officer Yanez testified that if appellants had said something like, “Come in. We can’t come to the front door”, he would have yelled to the officers to go in.
A.R.S. § 13-3916(B), provides in part:
“B, An officer may break into a building, premises, or vehicle or any part thereof, to execute the warrant when:
• After notice of his authority and purpose, he receives no response within a reasonable time.... ”
The “knock and announce” rule serves two basic purposes: protection of the individual’s right to privacy in his home and reduction of the possibility of harm inherent in an unannounced entry. People v. Webb, 36 Cal.App.3d 460, 111 Cal.Rptr. 524 (1973); Commonwealth v. DeMichel, 442 Pa. 553, 277 A.2d 159 (1971) and see Annot. 70 A.L.R.3d 217 at 227 et seq. See also Annot. 21 A.L.R. Fed. 820. As was stated in Commonwealth v. DeMichel, supra:
“ ‘... Regardless of how great the probable cause to believe a man guilty of a crime, he must be given a reasonable opportunity to surrender his privacy voluntarily.’ [citation omitted] ... Accordingly, even where the police duly announce their identity and purpose, forcible entry is still unreasonable and hence violative of the Fourth Amendment if the occupants of the premises sought to be entered and searched are not first given an opportunity to surrender the premises voluntarily, [citation omitted]” 277 A.2d at 163. (Emphasis in original)
The issue is whether appellants still had an opportunity to surrender the premises voluntarily even though they were standing with their hands in the air pursuant to Officer Yanez’ command. We first note that the announcement here was made loudly enough so that it was fair to infer that anyone inside the house also heard the words. Cf. United States v. Mendoza, 433 F.2d 891 (5th Cir. 1970). There was no testimony here that they did not hear the announcement. Even though appellants had their hands in the air, we still believe that they had an opportunity to speak and voluntarily surrender the premises. Had they yelled something out to the officers at the door or to Officer Yanez, the entry could have been made without the necessity of breaking down the door.
Appellants also argue that the officers did not wait for a reasonable time before they broke the door down. What constitutes a reasonable time depends on the circumstances of each case. State v. Bates, 120 Ariz. 561, 587 P.2d 747 (1978); State v. Dixon, 125 Ariz. 442, 610 P.2d 76 (App.1980). Here, appellants were in plain view of Officer Yanez and had ample opportunity to say something before the door was broken down.
On our own motion we have raised the issue of the trial court’s jurisdiction to place William Wright on probation for three years and withhold designation of the offense as a felony or misdemeanor. In State v. Risher, 117 Ariz. 587, 574 P.2d 453 (1978), the court held this could be done when the defendant was found guilty on an “open-enid” offense (one which could be treated either as a misdemeanor or felony). The court in Risher based its decision on A.R.S. § 13-1657, which has since been repealed by the new criminal code. We no longer have open-ended offenses, and the classification of a crime as a felony or misdemeanor is regulated by A.R.S. § 13-105 (1978). In any event, perhaps due to Justice Holohan’s incisive dissent in Risher, the
