Rules that prohibit the carry of firearms result in mass casualties when a law breaker instigates and active shooter situation.  By allowing all of the already vetted employees and law abiding citizens who work in and visit these buildings, such catastrophes can be avoided. 

Policies like these identify easy targets for terrorists and criminals looking for a soft target.  Please do not put the executive branch employees at risk.  They should be able to choose for themselves whether they wish to carry at work or not.
