So, to summarize, if the gun is resting on top of his pocket then it's in his lap. But if the gun is on the other side of the pocket fabric, less than 1/32" away, it is no longer in his lap.You are just playing games. When people say something is on their lap the commonly understood meaning, among non-knuckledraggers, is that it is on their lap outside of their clothes.
The gun was in his pocket. It was at no time visible to the policeman
Is that about right?
