It took about 30 seconds for me to find out about the flooding history of the river in question.
"The Guadalupe River has experienced major flooding more than a dozen times in the last century, with notable events in 1932 and 1987."
So it averages out to more like 120+ times in a thousand years.
But even if it was true that there was no way anyone could have known the danger, a psychologically normal person would have expressed sorrow and said he understood the grief of those who'd lost loved ones, many of them young children. But he doesn't understand. He's a full-on sociopath who feels nothing for anyone. He's pissed off not just by the accusation that his gutting of public services might have contributed to this tragedy, and represent a warning of tragedies to come, but by the very expectation that he be required to even pretend that he gives a ◊◊◊◊ about any of those dead people and their families. As he's sitting there, I'm sure he's bored and thinking about how soon he can get to a golf course.
