Trump once more proved the hard-political truism that when presidents speak out on a heinous racial killing or violence, their words have weighty consequences.

Trump was just following a well-worn template that the GOP has used for ages when it comes to a racist crack, dig, slur, or in this case a racist — and very violent — march by white racists.

The added element in the Arbery murder is that there’s another script in such cases that Trump can borrow from.

Like past presidents who have spoken out on racial violence and gotten action, Trump presumably wants it here, too.

Trump’s words on Arbery assure that action will happen in the case.
