Closing arguments are being made in the case of a Wisconsin gun shop that is being sued by Milwaukee police officers for millions of dollars for negligence in selling a gun that was used to wound one of the officers.

The case is important because it could set a precedent for gun laws if jurors decide that gun shop owners are financially responsible if a crime is committed using a gun purchased at their shop, according to an Associated Press report.

The plaintiffs, Officers Bryan Norberg and Graham Kunisch, were shot by a gun purchased by a straw buyer, which is someone who gets a gun legally on behalf of someone who can’t get it legally.

The owners of Badger Guns and Badger Outdoors said in their closing arguments yesterday that there was no negligence involved in selling the weapon, and that the clerk was deceived by the straw buyer.

The officers’ lawyer, meanwhile, countered that the clerk should have figured out that it was a straw buyer due to the buyer’s behavior and improperly marked forms.
