I don't think you are right with that argument BH. I clearly saw the bump in real time and on replay. There is really no reason why the ref and TMO should not have seen it too and considered it in their decision.
If nothing else, this matter highlights a couple of issues imo. First of all, there is too much interference with chasers, and the action by ALB should have been (maybe would have been but probably doubtful), a penalty to France had the collision with Barrett not gone so wrong. The second issue is that collisions in the air can be, and this one was, an accident. There was no intent to take out the other jumper nor to harm him. Accidental collisions do not warrant a red card in any circumstances regardless of outcome.
