I too truly can come up with no way they can know this for sure about the five feet. I sit here and look at my 12 inch floor tiles and count 5 of them for 5 feet fro my door and picture it. He is barely inside the door. I am trying to picture this with shooting Jim and I would think he would then be next to his body in which case would you not have possibly stepped in some blood, etc. Footprints may not be DNA I understand but that seems a bit messy with a chance of some type of transfer. Then you shoot Denise from five feet in and she has no chance to run around a corner? And then you tell Jayme to come to you (perhaps pointing gun at her) and she just happens also to be standing in sight also just docilely waiting and comes to you? I don't know... Perp could not have asked for things to go any smoother aside from the 911 call.
In think the 5 feet thing is just more semantics possibly or maybe an omission of there was a second perp at the back, etc.
I know the kicking in of the door has been discussed ad nauseum but just a question. If Jim was trying to hold it shut versus someone trying to kick it in and push it in, wouldn't he have the advantage? Or no? Meaning would it have to take some possibly younger and stronger than he? Thoughts? Or is kicking it in far easier than trying to hold it shut?
ETA: Forgive the typos, the coffee has not kicked in yet
