A jury in the Suffolk Superior Court convicted the defendant of trafficking in cocaine. On appeal, he *44 challenges the denial of his pretrial motion to suppress evidence seized pursuant to a warrant. We conclude that the evidence should have been suppressed.
The warrant in question, which contained a “no-knock” provision, was executed at an apartment in the Dorchester section of Boston on April 23, 1987. Upon arriving at the apartment, the officers beat the door down with a sledgehammer, while yelling “police.” The officers rushed into the apartment, and found the defendant coming down a staircase from the second floor. While one of the officers secured the defendant, the others searched the apartment. In a second floor room they found, lying on a table in plain view, a substance which later was determined to be 131.80 grams of cocaine. The officers also found other drugs and drug paraphernalia in various places throughout the apartment. Aside from the defendant, no other person was found in the apartment.
In his motion to suppress, the defendant argued that the application provided the magistrate with no factual basis for including a “no-knock” provision in the warrant, and that it therefore violated the principles set forth in
Commonwealth
v.
Scalise,
Subsequent to the motion judge’s decision, we decided
Commonwealth
v.
Amendola,
Although not constitutionally required, the so-called “knock and announce” rule has long featured prominently in our common law. See
Commonwealth
v.
Sepulveda,
In
Commonwealth
v.
Manni,
We agree with the Commonwealth that, as a general rule, the mere fact that an unlawful search and seizure has occurred should not automatically result in the exclusion of any illegally seized evidence. See, e.g.,
Commonwealth
v.
Rutkowski,
There is no basis to excuse compliance with the law in this case. The affidavit prepared by Police Officer Kenneth C. Dorch, who applied for and assisted in the execution of the warrant, contains no information which would support a “no-knock” provision, and the record is devoid of any showing of special need to dispense with the requirement. In executing the warrant, the police officers battered down the door to the apartment with a sledgehammer while announcing their presence and burst into the dwelling. This activity, which was aptly characterized by the defense at the hearing on the motion in the Superior Court as “sledgehammer and announce,” strikes at the very core of the safety, privacy, and personal property interests that the “knock and announce rule” is designed to protect. There exists a clear and substantial violation of a settled rule which if excused would tend to vitiate the rule in its entirety.
There is also no basis for application of either rule argued for by the Commonwealth. An inevitable discovery rule
*47
“ ‘should be applied only when it is clear that “the police officers have not acted in bad faith to accelerate the discovery of the evidence in question.” ’ ”
Commonwealth
v.
O’Connor,
The judgment of conviction is reversed and the verdict is set aside; the order denying the motion to suppress the evidence seized under the warrant is vacated; and an order shall be entered allowing the motion to suppress. The case is remanded to the Superior Court to determine whether the Commonwealth has any possibility of meeting its proof, see
Commonwealth
v.
Kirouac,
So ordered.
