A lot of times with domestic violence the women calls the police and then changes her mind down the line,sometimes women lie completely. The cops can be over zealous and over charge people,if what your brother saying is true he should have a chance at a dismal or at least a plea bargain that would result in a reduction to a charge that is a lot less serious. Men beat their wife or gf,then gf keeps quiet and down the line it gets worse. The state is aggressive with these type of charges but like I said sometimes a men can get the short end b.c the female is just rail roading him.
He need to discuss his options with his lawyer and fight the charges. Once the police arrest him they're not just gonna go o we messed up and drop the charges. The court process can be very drawn out,it can take a lot of time.
