Gun enthusiasts by the thousands are in Indianapolis for the National Rifle Association annual convention.
NRA Executive Vice President and CEO Wayne LaPierre went after critics of the NRA's proposal to put armed guards in America's schools.
"History has proven again the truth that President Obama and anti-freedom activists everywhere deny and try to suppress the truth that firearms - in the hands of good people - save lives," said LaPierre.
Indiana Governor Mike Pence also spoke at the convention.
Pence says Indiana was one of the first states to allow concealed guns in state parks.
The NRA convention runs through Sunday.
