But I didn't see anything in that description that was against serving the public. The only way to serve the public at that point in time was launching an investigation, not making super preliminary statements about what could have gone wrong and who could have been hurt.
I wouldn't say the tone deafness itself is a significant sign of corruption.
So the reason to think corruption is that there's no other reason to say that?
Well that's not true. Incorrectly blaming a particular company in the heat of the moment could lead to harm or harassment, and it's good to remind people to wait for a real investigation. The last thing the DOT wants at that point is even more avoidable mistakes.
And if it was motivated by corruption that statement seems like a bad idea. It draws a lot of attention to that specific contractor while telling people to wait for the investigation. If they are at fault, that extra attention is bad for them in the long run.
Did they ever figure out who was sleeping with whom/who was related to whom?
