In the 16th minute "Robin" pulls out a gun, the gun's safety slide is on the right side of the gun which means it's a left-handed version exclusive to people who are left handed , but "Robin" is right handed. (the safety slide is designed to be switched by the dominant hands thumb) In fact, the type of gun Robin keeps in her purse is equipped with an ambidextrous thumb safety, so the shooter can operate the safety regardless of being left or right handed.
Marshall mentions statistics that indicate owning a gun is generally less safe than not owning one. As a licensed attorney, Marshall would understand the distinction between correlation and causation. In other words, just because statistical data may demonstrate a trend between gun ownership and injuries (correlation) that does not actually mean that gun ownership is actually unsafe (causation). Statistical trends do not force a certain percentage of people to behave unsafely with firearms, nor do statistical trends actually cause injuries.
