Let's not forget that Obama immediately used the Dallas shootings as an opportunity to aggrandize gun control at the same time. During his Paris release he also said:

"We also know when people are armed with powerful weapons, unfortunately, it makes attacks like these more deadly and more tragic, [...] In the days ahead, we will have to consider those realities as well. In the meantime, today, our focus is on the victims and their families."

I don't know if that's something I would consider to be in the wheelhouse of what the president should do, as it reads like exploitative base rallying to me, which is something I've accused Trump of as well. I get it, never waste a good tragedy and all that, but it seems modern presidents are far too open about using tragedy to push an agenda.
