I firmly believe the Ramseys are innocent!
I do not have access to the Ransom note to determine pen pressure ,but from the overall appearance it doesn't appear to be written by Patsy IMO.
There were no bleed through pages on the pad but,several were missing,as though the perp took the pages for this purpose. Why didn't he just take the entire pad? It's almost as though he ripped the pages and took them with him in a folder or something to keep them neat until he returned them to the house. No one asked the right questions early enough to jog the memory of the Ramseys. Who may have grabbed a pen and the pad to run to a phone in private while visiting? Then later a folder appears which includes a picture of the entrepreneurial mag photo of John,with a heart around him? Was it ever determined if this folder was theirs? In fact,did the police release the "leak" deliberately to add to the already building public case against the Ramseys,was this "leak" truth? Were the pages absolutely from that pad,or was another pad taken from the home. We know,for fact,that the Pughs helped themselves to pads and pens from the Ramseys,can we be certain this pad was the one? It would have been a nice "gesture" (ha) on the part of the police to have confiscated the pads from the Pughs,but heck they didn't want to seem insensitive at this time,when Linda was obviously upset and her inebriated hubby was asking if Jonbenet was strangled.
They should have asked Linda,how many people may have stopped in the kitchen,both adults and children,who could have grabbed a pad to write a note,and left with one.
JMO IMO
