For example, if I go out to the local tavern and get blotto, then take a pool cue and brain the local cop (who comes to take me to the drunk tank) to death with it, I will be charged with: public drunkeness, assault, battery, assaulting a peace officer, possibly battery on a peace officer (if that's a seperate statute), resisting arrest, destruction of private property, and whatever else the local DA can tack on. All different criminal elements arising from the same incident. Read your Sunday morning police blotter, you'll see it all the time.
