Well I pretty much knew that I couldn't be making crystal meth in my house. I know that it is legal for me to cut wood down on my property and make a bat on my lathe. I know it is illegal to hit someone with my new bat about the head repeatedly until they are dead. It isn't immediately obvious what my intentions are when I cut the tree down. It still isn't obvious what my intentions are when I fashion a bat out of it.
It is however, pretty obvious what my intentions are when I request a 72 mhz TX JR crystal on channel 56 and a JR TX battery. It's going in a TX. I know, maybe the person will take the new crystal to a certified radio repair shop that just happens to be within driving distance which just doesn't make sense. A person would just send the radio in and have it tuned there.
