I really think that you are placing too much importance on a confession by JP. It's got to the point that it's been posted that anyone who helped JP pack up his, his wife's and his two boys' things but didn't confront him on why he won't go to the police station, they are "enablers". He has a constitutional right to not incriminate himself. There are U.S. soldiers dying on a regular basis to protect that fifth amendment right. Yes, the police always want a confession, but they never sit around criticizing family and friends of the suspect if they don't get one. They do sometimes bring a parent of the suspect into the police station to try and convince a suspect to confess. And yes, the Police are always grateful when friends and/or family convinces a POI to come in for questioning. But to vilify the neighbors and friends because they won't confront a very likely murderer, and to claim that it would be easy to do so - no, that's absurd. If they can't get a confession, then the police will simply focus their case on the evidence. If JP is tried and convicted of murder without ever confessing, he wouldn't be the first person in that position - not by a long shot.
