Its training required to be certain types of Security within SC. It teaches everything from handcuffing, to shooting, laws, frisking etc etc. Pretty nice course. Just havent found one local to me. pro1
I don't know anybody in the Charleston area. However, Steve Cooper with Paladin Training in the Florence area does train security & LEOs. He used to do classes at the local tech college. But, I think most all his class & range training is done at the Darlington County Sheriff's Range now. (This guy & his team are PRO's all the way!)
Here's his FB link- You won't see much about the LEO & security training publicly posted. So, you need to contact him.
