“Smart guns” have technology that can recognize the fingerprint or grip of an authorized owner and guarantee that they’re the only person able to fire weapon. They’ve been around for a while, but haven’t been made commercially available in the U.S. due to opposition from gun advocates. Now, though, that might be about to change — thanks to Obama’s recent executive actions on guns. “If we can set it up so you can’t unlock your phone unless you’ve got the right fingerprint, why can’t we do the same thing for our guns?” Obama asked during the heartfelt speech in which he laid out his new gun policies on Tuesday (Jan. 5). “If there’s an app that can help us find a missing tablet … there’s no reason we can’t do it with a stolen gun. If a child can’t open a bottle of aspirin, we should make sure that they can’t pull a trigger on a gun.”
