How do you think this happened?

[Catfish]

Years ago 2 guys stopped at the house and ask to hunt rabbits. I gave them permission slips and ask if they would like for me to show them where they could find some, they say yes. So we started accrossed the corn field and I looked at one of them who was carring a single shot .410 and it looked like his hammer was back. Not believing it I looked closer and it still did so I ask his if his hammer was back, he said yes. I ask why and he said so he could get off a fast shot. This is when I told him if he didn`t have time to cock his gun he didn`t have time to get a shot off anyway and told them to get off my property and never come back, and ran for the house!
