Lulu is trying to help a recently released inmate get back together with his wife who is intent on divorcing him. In the episode, the ex-con is revealed to have been incarcerated for shooting the owner of a liquor store. Since he had been in prison in Pennsylvania for this crime, presumably the crime occurred in Pennsylvania. The problem is that ALL liquor stores in Pennsylvania are owned by the state, so unless a way was found to shoot and wound a non-living entity, the crime is impossible. Obviously poor research by writers who tend to know too much about L.A. and New York and not much else.
