Pardon my rant, but...
People say "baton" and I always think of the lightweight tube runners carry around a track. In this context, a baton is a nightstick. Have you ever examined one? A friend showed me his grandfather's. It was about 2 feet long, made of cherry, and filled with lead. It would break down a door or ruin a car. It would certainly break bones. With the lead weight and small diameter, it would be more effective (lethal) than a baseball bat.
"Baton" is just a euphemism that papers over extreme violence.
