Lesson details

Key learning points

  1. It is illegal to carry a knife or offensive weapon without a reasonable excuse, even if you don’t intend to use it.
  2. The law covers a wide range of weapons, not just knives (for example, items that are disguised as everyday objects).
  3. Online sales of knives and weapons are regulated, but attempting to buy or sell illegally is also a crime.
  4. Weapon-related crime and possession carries serious consequences.

Keywords

  • Offence - a breach of a law or rule; an illegal act

  • Possession - having something that belongs to you or is under your control, such as keeping an item, weapon or other object with you or in your care

Common misconception

If I carry a knife or weapon but don’t use it, I won’t get in trouble.

Carrying a knife or weapon in public without lawful reason is a crime regardless of intent. Police can and do take action even if the knife or weapon isn’t used.
