In an increasingly violent America where guns on average kill 100 people each day, experts say companies involved in selling, making or distributing guns should take a new look at their legal risks.

There are signals that some companies are looking at these risks. Dick’s Sporting Goods announced in March it was pulling guns and ammunition from 125 of its more than 700 stores. The company’s general counsel was not available and a spokesman declined comment on its policies. The giant retailer Walmart Inc., which is facing possible lawsuits after a mass shooting at its El Paso, Texas, store Aug. 3, also is weighing its options on guns.
