The Shooting Gallery: President Obama yesterday promised he would “politicize” the issue of gun control after the latest mass shooting in Roseburg, Oregon, “because our inaction is a political decision that we are making.”

The shooter identified as 26-year-old Chris Harper Mercer had six guns during the attack, spare magazines, a bulletproof vest, and seven more guns at home. In all, Mercer had owned 14 guns, all bought legally from a licensed federal firearms dealer. Mercer has been described as a reclusive, angry young man with a grudge against organized religion.

Obama got into a long-distance verbal clash with candidate Jeb Bush, who was almost dismissive about the shooting. “Look, stuff happens,” Bush said in South Carolina. “There’s always a crisis, and the impulse is always to do something and it’s not always the right thing to do.”

The President said, “The American people should hear that and make their own judgments based on the fact that every couple of months, we have a mass shooting. They can decide whether they consider that ‘stuff happens.’ ”

Econ 101: Stocks dropped sharply then bounced up yesterday after a disappointing report that the economy added only 142,000 jobs in September. The unemployment rate stayed at 5.1 percent.

Adding evidence that the economy is a little soft, the August jobs report was lowered from 173,000 new jobs to 136,000. Some analysts say this news may force the Federal reserve to delay a rise in interest rates until next year. All of this brings a kind of mushy uncertainty to the economy and big investors hate that.

But Sunday’s heroes have run up a long record of arrests for DUI, sexual battery, domestic abuse, and even killing an ex-girlfriend’s dog.
