If you moved mine I would just pull your rollaboard out and leave in the aisle. Making yourself the luggage police won't get you far with many passengers. If there were nothing but roller bags in the bins there would be no room left for others coats and briefcases. Just because I choose to only carry on a briefcase doesn't mean that you should get free and clear foot wells while I suffer with a bag beneath me.

My vote is every man, woman and child should fend for themselves. If you board late or the bins are full, tough luck.
