Chucking it in the swamp is the easy way to go but still reckless. It could show up again and kill somebody. Even though they could not connect the dots to you, it would still be blood on your hands.
I KNOW I will get flamed for this but, Ya'll may recall an encounter I had with BATF about a year ago over a tear gas baton that I found in my grandfathers possessions, and that I indeed did call them to make sure I was not breaking any laws by selling it on Gunbroker. I'm a gunsmith and had a LOT to lose by pissing BATF off. It was an illegal device and was informed by them that they would come and get it and dispose of it. I took a LOT of heat here for doing that. However my experience with the BATF special agent was a very positive experience. No jack booted guys jumped out of a black helicopter or nothing. Nobody threatened me or treated me like a criminal. Actually the agent was about my sons age, 30's, dressed like a normal person, no black suit and shades, and was courteous and respectful. If you have not taken possession of this device DO NOT and just go about your biz. If you have, GET RID OF IT. Just call BATF they will get it off your hands. If you are scared your experience will not be as good as mine, have a lawyer present, at the least have their phone number ready. You can tell your friend what you have found out here and let him make the choice of what to do, but if you do not have it in your possession, for God's sake don't go near it. You can see the tangled web it forms.
