Edition: 2009
Statute: G.L. c. 269, § 10(b) (second clause)
Scope note: This offense is inapplicable to firearms, rifles, and shotguns (covered by § 10a) and to the per se dangerous weapons listed in the first clause of § 10(b) (see Instruction 7.680). This covers other "dangerous weapons" found on a person during arrest.
The Commonwealth must prove four things beyond a reasonable doubt:
Must be either arrest on a warrant for an alleged crime, or arrest without a warrant while committing a breach or disturbance of the public peace.
Purpose: Statutory purpose is to ensure the safety of arresting officers. O'Connor, 7 Allen 583, 584 (1963).
Complaint must charge this element: A complaint that does not charge the first element charges no crime. Blavackas, 11 Mass. App. Ct. 746, 752-753 (1981).
Dangerous per se: An item which, by its nature, is capable of causing serious injury or death. Judge instructs as a matter of law.
Not dangerous per se: An item is a dangerous weapon if used in a way that it reasonably appears capable of causing serious injury or death. Jury may consider circumstances of possession, nature/size/shape, and manner of handling.
Not every crime is a breach of the peace. Examples:
- Is a breach: Affray, assault, disorderly conduct, OUI (Gorman, 288 Mass. 294, 298-299 [1934]), high-speed traffic chase (Cavanaugh, 366 Mass. 277, 280-281 [1974])
- Not a breach: Possession of short lobsters (Wright, 158 Mass. 149, 158-159 [1893]), illegal sale of alcohol (Lennon v. Richardson, 15 Gray 74, 77 [1860])
Possession of billy (Note 1): Statute also specifically punishes possession of a "billy" when arrested. Instruction should be adapted if alleged weapon is a billyclub.
Knives as dangerous weapons (Note 2): Straight knives are typically dangerous per se. Folding knives without a locking device typically are not. Possession of a closed folding knife is a dangerous weapon only if used or handled in a manner that made it dangerous. Turner, 59 Mass. App. Ct. 825 (2003).
