this   is not the thread youre thinking of. i cant find it either but basically there was a french national anon who had a black powder revolver and successfully used it to defend himself in a home invasion against two melanated future doctor-lawyers. said it worked well and the law - while pissed off he had survived and merked two niggers - couldnt touch him.  definitely a good and viable option for those anons who cannot legally own a firearm.
