Landing on 24L, and probably instructed to hold short of 24R, the crew of the Eagle ERJ145 would be staring at two sets of flashing red lights on each side of the taxiway, as well as red lights right across the taxiway.
These lights are extinguished when clearance to cross is issued.
I can't imagine anyone taxiing between and right over these lights, without at least confirming the clearance. They are very bright, and pretty obvious their intent.
It is Air Canada SOP, when operating at an airport so equipped, (LAX
also comes to mind) that the pilots must state and confirm, "We have the verbal, we have the visual, we are cleared across". Without either you do not move.

Just because I stopped arguing, doesn't mean I think you are right. It just means I gave up!
