I'm sorry to hear of this accident, Rickey, and hope that the injured dancer is going to be okay. I cannot speak to the other questions you raise, but I will use your unfortunate incident as an opportunity to encourage callers to carry liability insurance.
Caller's liability insurance offers some protection in case you get sued as the result of an accident. (It is also increasinly necessary to show such coverage as a condition of renting many halls.) It is available at minimal cost through Callerlab, the national association of square dance callers, and members of the Lloyd Shaw Foundation and/or Country Dance and Song Society are eligible to purchase it. You can find an overview of the CDSS arrangements here; http://www.cdss.org/membership.html#membcallerlab For CDSS, contact Caroline Batson ([email protected]) for more information. David Millstone
