Appeals court hears challenge to prosecution's closing argument in sexually dangerous person case

The Appeals Court heard arguments in Commonwealth v. Robert Earl, an appeal from a jury adjudication under the Sexually Dangerous Person (SDP) statutes. Edward O'Brien, counsel for Robert Earl, asked the panel to overturn the commitment on the ground that the prosecutor's closing argument was unduly inflammatory and risked 'tainting' the jury's consideration of the central statutory question: whether Earl posed a present risk of reoffending.

O'Brien focused on two types of allegedly improper argument. First, he argued the prosecutor's opening sentence that the defendant 'committed despicable, horrible things to three innocent victims' was an inflammatory appeal to emotion. O'Brien said the remark and subsequent analogies (the prosecutor compared the risk to 'a looming disaster, a tornado') exceeded permissible argument and that, because the defense did not object to the initial phrasing, only a substantial risk of miscarriage of justice would justify reversal.

Second, O'Brien attacked the sufficiency and weight of the Commonwealth's expert evidence. He emphasized that the most objective predictive measure in the record, the Static-99 actuarial score, placed the defendant in a low recidivism band (roughly 4'—3% at five years, 6% at ten years according to the experts); defense counsel argued that the Commonwealth's other evidence was largely subjective and that the jury had been told by one expert that his subjective judgment was 'worth as much as a coin toss.

The Commonwealth, represented by Stacey Goth and later by Rob Kidd, defended the remarks and the evidence. Kidd argued the jury was instructed that closing arguments are not evidence and that the judge gave a curative instruction telling jurors not to decide the case based on sympathy or emotion. On the tornado analogy, the Commonwealth said the jury could consider both the likelihood of reoffense and the seriousness of potential harm; it relied on precedent (Commonwealth v. Boucher and others cited in argument) allowing consideration of seriousness to inform risk assessment.

On the actuarial and expert evidence, the Commonwealth pointed to testimony by its qualified examiners: two different examiners placed Earl's risks in roughly similar bands and described treatment gaps. The prosecution urged that the Static-99 and clinical testimony, taken together, allowed the jury to find the statutory risk threshold.

Ending: The panel heard fact- and law-focused questioning about whether the prosecutor's rhetoric rose to reversible error in the absence of objection, and about how juries should weigh actuarial scores versus examiner testimony. The case was submitted for decision.
