I don't think so. The only thing that appears to be missed was an attempt to extend the concept of the defense being able to introduce prior conduct and convictions of the person defended against, even if the defender did not know it at the time, into evidence. Adjutant makes it clear that is allowed for homocide cases, but does not explicitly extend (or not extend) the concept to cases involving lesser offenses.
There are competing schools of though on introduction of prior conduct of the assailant that was unknown to the defender at the time of the incident.
1) The person claiming self defense did not know of the prior conduct, therefore it did not enter into the decision making process, therefore irrelevant.
2) Useful in a defense case to establish credibility as to the allegation of assault, therefore relevant and admissible.
#1 has generally been the philosophy of the courts, however, Adjutant adjusted that in MA. I think is was an appellate court, not the SJC.
The defendant was alleged to be the aggressor since he spoke to the person making the threats about littering.
