Bet the killers are fairly young. I could imagine them saying to each other : " let's leave them hanging out by the pool " a sadistic joking kind of vibe. Just my opinion though...
With all due respect, I see your point, but
I doubt that inexperience, and/or youth was involved, as far as the killers were concerned. This was IMO a very professional, contract hit, and they sent some of their best. Like the FBI Profiler said from the beginning, someone was sending a message by leaving them hanging. They could have just quickly shot them in the back of the head, and left the bodies where they fell.What is the message, and to whom was it sent ? I certainly think it was a warning that others, like the Shermans, need to obey certain cultural expectations, and business rules. IMO the message was to the very rich, who fund raise in the millions, and get involved with politicians, and Big Pharma high level decisions, and deals. I don't mean to repeat myself, but I still think that leaving them hanging on display, side by side, in a half sitting postion, with their necks tied to pool railings by men's leather belts, makes a statement about shaming this couple, and their family. That shame may be evident to the Jewish Community at large, because in their culture, death by hanging implies a divine curse. Possibly whoever ordered the hit felt that somehow they deserved a curse, which justified their deaths. Why, I do not know. It could be family ( the orphans ), angry business associates, or because of deep political issues. It bothers me too that Honey suffered injuries before death that caused so much bleeding, and that she was quite possibly already tied up when it happened. Did someone especially hate her, even more than Barry ? She had such a good, kind reputation, it hardly seems possible, but we know so little. Was she tortured to make her give her killers some information, or maybe call Barry on the phone, so he would come home, or was it done just so Barry would see that horror as the last thing before he died ? The people who ordered this hit were very angry, full of hate, and wanted to make sure that everyone understood that even the privileged elite have to live by certain rules, and obey a chain of command. It may even be more about power and control of those who move in those circles, than it is about hate. The professional assassins who left no trace, have left long ago. It takes real talent, planning, and expertise, to enter and leave a house in a wealthy neighbourhood without ever being seen, or captured on video. They may even have been in another country before the bodies were discovered. Those who sent them are so powerful, rich, and protected that I doubt they will ever be found. I have no idea if they are in Canada, or another country, or who they are. Unless there are some real surprises, I don't think we will ever know what exactly happened to The Shermans that night, or who killed them. It will likely remain a great Canadian mystery. IMO
