Why Do Gunmen Target Churches And Schools, Not NRA Meetings?
In the wake of the heinous attack on Charleston’s Emanuel American Methodist Episcopal Church, Democrats’ ritual calls for more gun control have louder than usual, and a mainstream media’s focus on the threat of “mass shootings” has been kicked up a notch.
The question none of the Democrats or media outlets have asked is why gunmen, historically speaking, attack churches and school but bypass NRA meetings?
Why do they target Fort Hood twice within a five years period while opening fire in Walmart remains unpopular?
To ask the questions is to answer them.
Law-abiding citizens are largely prohibited from possessing guns for self-defense in churches and schools around the country, but they may be heavily and openly armed at an NRA meeting.
Likewise, soldiers are then mandated to be unarmed on stateside military bases while law-abiding shoppers at Walmart can and frequently do carry guns to protect themselves and their families.
