The Gang Wrestles for the Troops
Criminal Activities
Assault
Threatening another with imminent physical harm or displaying a weapon in a manner that puts others in reasonable fear of harm; in many jurisdictions brandishing a firearm or threatening violence is a criminal offense.
Situation:
"During the improvised wrestling match, Cricket repeatedly throws sand into opponents' faces/eyes and attacks other participants in the ring, constituting an intentional physical attack and battery."
Theft by Deception
Collecting money (cash/cashier's checks) from students for an acting class or services, then closing the business and refusing refunds can constitute theft by deception / fraud under U.S. law when the payer was induced to pay by false or misleading representations or when the operator intends to deprive payors of their money.
Situation:
"Members of the Gang tell the venue the event is 'for the troops' and receive a discount; this was done to obtain a lower price by misrepresenting the purpose of the booking."
