Instruction 7.700, Criminal Model Jury Instructions for Use in the District Court
Carrying a dangerous weapon when arrested (G.L. c. 269, s. 10 [b])
CARRYING A DANGEROUS WEAPON WHEN ARRESTED
The defendant is charged with carrying a dangerous weapon (on his
[her] person) (under his [her] control in a vehicle) when he (she) was
arrested (on a warrant) (for a breach of the peace).
Section 10(b) of chapter 269 of our General Laws provides as follows:
“[W]hoever,
when arrested (upon a warrant for an alleged crime) (while
committing a breach or disturbance of the public peace)
(is armed with) (has on his person) (has on his person or under
his control in a vehicle)
a. . . dangerous weapon. . .
shall be punished. . . .”
To prove that the defendant is guilty of this offense, the
Commonwealth must prove four things beyond a reasonable doubt:
First: That the defendant was (arrested on a warrant) (arrested
without a warrant for committing a breach of the peace);
Second: That at the time of his (her) arrest the defendant (was armed
with [alleged weapon] ) (had [alleged weapon] on his [her] person) (had
[alleged weapon] under his [her] control in a vehicle);
Third: That the defendant knew that he (she) was carrying the
[alleged weapon] (on his [her] person) (under his [her] control in a vehicle);
and
Fourth: That the [alleged weapon] was a dangerous weapon.
A dangerous weapon is an item
A. If the alleged weapon is dangerous per se.
which, by its nature, is capable of causing serious injury or death. I
instruct you that, as a matter of law, a ___________ is a dangerous weapon.
An item is a dangerous weapon if
B. If the alleged weapon is not dangerous per se.
it is used in a way that it reasonably appears to be capable of causing
serious injury or death to another person. In deciding whether an item is a
dangerous weapon, you may consider the circumstances under which it
was possessed, the nature, size and shape of the item, and the manner in
which it was handled or controlled.
Commonwealth v. O'Connor, 7 Allen 583, 584 (1963) (statutory purpose is to ensure safety of
arresting officers); Commonwealth v. Blavackas, 11 Mass. App. Ct. 746, 752-753, 419 N.E.2d 856,
859-860 (1981) (complaint that does not charge first element charges no crime). For cases on what
constitutes a “dangerous weapon,” see the notes to Instruction 6.300 (Assault and Battery by Means
of a Dangerous Weapon).
This model instruction covers the offense set out in the second clause of G.L. c. 269, § 10(b). Note
that this offense is inapplicable to firearms, rifles and shotguns (which are covered by § 10[a]) and
to the per se dangerous weapons which are listed in the first clause of § 10(b). See Instruction 7.680
(Carrying Certain Dangerous Weapons) for the offense set out in the first clause of § 10(b). See the
notes to Instruction 6.300 (Assault and Battery by Means of a Dangerous Weapon) as to what
constitutes a dangerous weapon.
SUPPLEMENTAL INSTRUCTION
In this case you have heard testimony
Breach of the peace.
suggesting that the defendant was arrested without a warrant for
committing the offense of [alleged offense for which arrested] . If it is
proved to you beyond a reasonable doubt that the defendant
committed that offense, I instruct you that as a matter of law
such an offense constitutes a breach of the public peace.
Not every crime is a breach of the peace. An affray, assault, or disorderly conduct
is a typical breach of the peace. Commonwealth v. Gorman, 288 Mass. 294, 298-
299, 192 N.E. 618, 620 (1934) (OUI is a breach of the peace). See Commonwealth
v. Cavanaugh, 366 Mass. 277, 280-281, 317 N.E.2d 480, 482-483 (1974) (high
speed traffic chase is a breach of the peace); Commonwealth v. Wright, 158 Mass.
149, 158-159, 33 N.E. 82, 86 (1893) (possession of short lobsters is not a breach of
the peace); Lennon v. Richardson, 15 Gray 74, 77 (1860) (illegal sale of alcohol is
not a breach of the peace). See also Instruction 7.200 (Disturbing the Peace).
