Dick's Chairman and CEO Edward Stack said on "Good Morning America" Wednesday that after the shooting the company "felt it needed to do something."

Stack says that the gunman, Nickolas Cruz, had purchased a gun at a Dick's store, but not the one used at the school shooting, even though all existing rules were followed. 

Stack says that the system that's in place won't stop sales to dangerous people and said lawmakers must do something.

Stack said Dick's is prepared for any potential backlash, but will not change its policies on gun sales.
