AFAIK, ensuring your own safe crossing is always your own responsibility regardless of any waving others may give you - you are the one making the decision to trust others' advice instead of verifying things for yourself.
At most, north inner might get cited for obstructing traffic since he is not supposed to stop on the left/fast lane unless he is either turning left or on a stop sign/light.
Blind left turns through oncoming traffic lanes are scary. One of my closest calls was when the driver behind a truck waiting on a left turn decided to change lanes in the middle of the intersection just as I was passing by the truck, half-way into my own left turn.
