Do they? I don't think there's anything more important for these particular politicians than representing the interests of their constituents.
There's a reason we have police and local authorities in addition to high-level politicians. They handle local politics and issues. If we actually need our state representatives so involved in something like this that they can't perform the functions they were elected for, then that's a systemic problem that should be addressed.
Is this a bit insensitive? Perhaps. But these people have a responsibility to look at the big picture, and if that means ignoring something tragic but not related to their responsibilities, they need to recognize that and act appropriately.
