Legal answer
Own a stun gun in United States: legal status
The United States does not have one nationwide stun-gun rule. Official state sources show state-dependent regulation: Massachusetts officially says stun guns are allowed but regulated, with official rules restricting access or use by non-licensed persons, while the same state also imposes safe-storage requirements and its official FAQ says a current license to carry is needed to purchase or possess a stun gun.

Conditions
What would need to be true

State-specific licensing, training, storage, or exemption rules may apply.
Penalties
Possible enforcement risk
Penalties depend on the state law that applies if a person purchases or possesses a stun gun contrary to that law.
Enforcement
How this is usually enforced
State and local police enforce state weapons laws, and licensing authorities may enforce permit-related rules.
