bored my gun 3 years ago in the pawn shop.the owner has no licence to sell guns so i go true all the backcheck and register in another pawn shop who have a licence. one month ago the first pawn shop owner ask my gun to see for two days, because he sad the police want to see the gun. i give to him and he said he not give me back because it was a mistake to sell me because he don't have a licence. i bring two police officer out to the shop and they told me if i want a gun sue him and left. the pawn shop owner still have my gun what i paid and registered in my name for three years . a police do nothing about this . what to do?
