An interesting article from the Seattle Times: http://seattletimes.com/html/localnews/2020325837_legislaturegunsxml.html
Some excerpts:
Carrying guns on the Capitol campus has long been allowed in Olympia. It’s seldom discussed, rarely criticized and speaks volumes about the debate over gun control this session.
In fact, Washington’s Capitol is one of the few in the country with no restrictions on firearms.
Of the 42 states that responded to the survey, only Washington, Texas and Kentucky indicated they had no restrictions on carrying weapons at their capitols. Eight states allowed people with concealed-weapons permits on campus, and the rest restricted firearms to law-enforcement and security staff.
Interesting to note the folks that support banning firearms on campus even though there has NEVER been an incident. Shows the predisposed bias (hoplophobia) that some inherently have against firearms - even though they are just inanimate objects.
