You know Bob - one road in also means only one road out!
It's not hard to see why people are abandoning religion in droves when it
serves to square the circle of violence with more fortifications.
The Washington, D.C. Temple is closed while being renovated. Designed a
half-century ago, it has security favorable geography; It sits atop a hill, and
has a single entrance off the only road that goes by. The hillsides, forested
and steep, provide no path for vehicles. This House of the Lord will
not be a soft target for terrorists! It has long been ready for any such threat.
Just like Captain Moroni fortified cities, another Moroni with a trumpet stands
guard over a temple on an easily fortified site.
