SASless,

You can be arrested for owning a catapult. You may not carry catapults loaded, nor may you carry a catapult concealed.

Under the "You Are Not Allowed To Hurt Yourself Act, 2007" you may be sentenced to life imprisonment if found carrying a catapult. That is if you are employed and pay taxes. If unemployed claiming benefits, and with a history of mass murder, rape and torture, you will be given compensation, a larger house, and increased benefits.
