The idea that he may have been a bomber is a bit nonsencical, such people are only displaying their crass ignorance and insecurities, I'd be embarrassed to have my name associated with such views with regard to this incident.
The driver did the wrong thing, there may be mitigating circumstances (like traffic) that prevented from praying at the terminus, you have to bear in mind that he can drive for five and a half hours without a break he may well have been running very late on a five hour first part, hence...
I feel management and staff would view this event with some humour and sensitivity and then move on.
