We don't know why the individuals were on the tracks.

They force pedestrians to pay attention.

We don't know why the driver made the decision to cross. It appears that everything was working properly. Again, that's all under investigation.

We don't really know what her motivations were. Right now we only know what the results are. Drivers need to take very seriously a crossing arm.

She drove around the crossing gates, apparently. The gates were down and everything was functioning as it was supposed to.

I just got tired of dealing with all the construction. It's about time. I need to be closer to home, but I don't want to stop.
