For these first 2 cases, it was shown LL had opportunity but in a very limited time frame. Operating in plain sight if you believe she is guilty, but still only a small window to attack.
However, it seems like in later cases they will be able to show greater opportunity and times when she was alone for significantly longer and its going to become increasingly more difficult to defend.
I am remaining on the fence until we have heard more evidence just to try and be impartial and objective but if they can't counter the medical opinion that it was deliberate then I just can't see who the defence can pin it in order to get LL aquitted.
I know they don't have to show someone else is guilty, just that LL is innocent but if jury buy the prosecution theory that it's deliberate harm, then they will almost certainly follow that it was probably LL who did it.
