Lieutenant Elwood Forbes:  Sorry to bother you , but I understand you told _ one _ of my men earlier about a guy in here buying guns and ammo . Could you tell me what he looked like ?
Gun Shop Owner: Like I told the officer on the phone , I do n't pay attention to how my customers look .
Lieutenant Elwood Forbes: Ca n't you try to remember ?
Gun Shop Owner: Well , he was a big man . Short hair , nice looking .
Lieutenant Elwood Forbes: Did you know him ? Have you ever seen him in here before ?
Gun Shop Owner: Like I told the officer who called , I do n't pay attention to how my customers look .
Lieutenant Elwood Forbes: Do n't you think it 's strange ? A man walks in here and buys a high - powered rifle , a shotgun , and enough ammunition to start World War III ? Would n't that make your attention ?
Gun Shop Owner: Look Lieutenant , I do n't choose the customers ! If a man walks in here and wants a weapon , we sell him one . If he wants two , we sell him two . There ai n't no law against that .
Lieutenant Elwood Forbes: Yes , but did you by any chance get him to sign the registration form for the purchase of the weapons ?
Gun Shop Owner: Of course . That 's the law .
