In order for you to see JRs motive in voluntarily and purposely giving PRs pad to LE, you must take yourself into their minds, as they were staging the death of their daughter to make it look like an intruder had came in their home that night, and killed her.
We see how they went to the ends of the earth to distance themselves, in particular, Pasty from the ransom note. We see it in her coming up with a grand story of how she jumped over the note on her way down the spiral staircase that morning, or in her own words "somehow got around it", instead of just picking up the pieces of paper that were spread out before her. She then says she bounded back up the stairs, without ever touching the note to check JB room and called for John. Then somehow they arrived on the floor with no creases, bends, fingerprints, or any signs of handling, all spread out perfectly on the floor when Officer French arrived 7 minutes after the 911 call.
Where are the creases? Where are the signs of the parents clutching the note, reading word for word?, where are the parents fingerprints?
Kinda convienant how Patsy somehow avoided touching the note on her way down the stairs, and on her way up the stairs, even though this note says "we have your daughter". Kinda too convienant that JR was on his hands and knees, reading the note as it "lay on the floor". So as you can see the parents did everything they could to not touch the note once their gloves were off and were awaiting LE to arrive. Why?
So when LE asks for handwriting samples that morning, JR purposely gives them a pad that he wrote on, and then gives them the ransom note pad, which was Patsy's pad, that had some of her writings, lists, etc...You may ask yourself why would JR purposely give LE the incriminating pad?
It's for the same reason why they left two practice notes in the trash bin(Dr.Henry Lee)and one practice note in the pad.
Still confused? JR and PR had to paint a picture for LE that an intruder had done this. So here is the reasoning:
JR knew that LE would find Patsy's fingerprints all over the notepad(which they did, 5 of her prints were found on the notepad). JR and PR knew that her prints were not on the ransom note, or the practice ones that were found. So by this fact, they made it look like an intruder had came in the house, sat down and with gloves on, wrote the note and when he "messed" up, he just tossed away the practice notes(showing he was there taking his time). The Ramsey's could now say that her prints are all over the pad but not the note therefore it proves she didn't write it, or her prints would be on it. JR could also say, I gave you that pad, do you think if we did it, I would have given you that pad? I'm not that dumb! This was a reverse psychology move. Now don't you see how it all comes together? Now do you see why it was so pertinent that they tell a story of how Patsy never touched the note? They tried to distance themselves from the ransom note bc they knew it was going to be hard to overcome. They did the same thing with the flashlight. They left it out on purpose for LE to find, but completely wiped it of prints to distance themselves from it. They overthought it.
I called it a "reverse psychology move" when I wrote this. It is a form of plausible deniability.
