President Obama was right about Ferguson when he told the American people last week, “We need to accept that this decision was the grand jury’s to make.”

If the president meant what he said, there are two immediate steps he would take.

First, he would tell Attorney General Eric Holder to stand down.

As former mayor and federal prosecutor Rudy Giuliani has noted, given that the grand jury found not enough evidence to indict Police Officer Darren Wilson for the shooting of Michael Brown, Holder ought to stand down in his attempt to bring a federal case.

Remember, several African-American witnesses have corroborated Wilson’s version of events, as did the forensic evidence.

Second, President Obama would never again have the Rev. Al Sharpton at the White House. In American life today, it’s hard to think of any figure more opposed to the idea of respecting a grand jury’s considered decision than our Rev. Al.

Certainly he showed that in Ferguson, immediately dismissing the grand jury’s decision because it wasn’t the indictment he’d demanded.

Closer to home, he also wants an indictment from the Staten Island grand jury in the case of Eric Garner, who died while resisting arrest this past summer.

At the same time, he’s linking what NYPD Commissioner Bill Bratton says was the accidental shooting of Akai Gurley with the Garner and Brown cases.

Now, it’s possible that some of the ideas President Obama discussed in his meetings Monday — e.g., $75 million in federal funding to get 50,000 body cameras to cops around the country — may be helpful.

But if we are talking about solutions that will save lives, it starts with the most basic: Tell people not to resist arrest or assault police.

The Rev. Al has been careful to say he condemns violence. But he also stokes the flames.

Missouri Lt. Gov. Peter Kinder wasn’t too far off the mark when he said this weekend that Sharpton “is an inciter of mobs, and he demands mob justice.”

And there should be no welcome for such a man at any White House.
