Here in America pranking people by scaring them with a baseball bat in hand is commonly called assault with a deadly weapon, and warrants deadly force used against the perpetrator. Unless you can run faster than 1500 ft./second you might want to think twice about "pranking" an American. They are sometimes armed, legally, and commonly know how to use any legally carried handgun.
An armed society is a polite society. It tends to cull out the criminally inclined young men early.
