I'm going to the extreme here, but if you're making a bomb or plotting to kill someone in your own house is that no one's business? BTW where are you fishing? A guide friend of mine who fished the back country out of Key West carried a mini 14 in his boat in case someone tried to hijack it. He told me that he fired a couple of shots over another boat that was approaching him in a suspicious way once. That was back in the early 80s.
