I am pretty sure there are several instances of people with a CCW license in a church that stopped and active shooter. As I recall there was a woman in Colorada that was a member of the church security team. She drew on a shooter and shot him. Another example was a minsters son that stopped a shooter using his concealed handgun.

Following an argument with friends a few blocks away, 29-year-old Kiarron Parker raced his car across the parking lot of the New Destiny Christian Center just as Sunday services had ended. His car rammed another and came to a stop. As the pastorís mother (67-year-old Josephine Echols) and others came to Parkerís aid, he pulled a gun and started shooting. Echols was hit 5 times and died. As people ran back into the church, Parker followed, but was killed as he entered the foyer by church member and off-duty police officer Antonio Milow.
