If the 9/11 attacks more than a dozen years ago taught Americans anything it all, they should teach us to be on high alert no matter where we live and what we’re doing.

Thus, warnings to mall shoppers have gone out across the country in the wake of a threat made against The Mall of America by an al-Qaeda affiliate, Al-Shabaab.

Yes, that means Westgate Mall in little ol’ Amarillo, Texas.

Al-Shabaab has threatened to strike malls in three western countries. Department of Homeland Security officials take the threat seriously. The Mall of America is in Minneapolis, which is home to a large Somali immigrant population. The Twin Cities region also reportedly has produced many recruits who’ve signed up to fight with Islamic State and other terrorist organizations.

Make no mistake, these threats go right to the heart of where we need to be alert. Malls represent — to many people around the world — some elements of American excess. Americans, of course, do not see it that way, nor should we. Do we stop doing business at these places just because a terrorist group has leveled a threat? Of course not.

But these monstrous organizations have shown how seriously the world must take their threats.

The 9/11 assault should stand as proof that these organizations mean business.
