Liberal Groups Rally on the National Mall

Story here.  There have been proposals for more monuments and for confining protests on the Mall to some sort of protest zone.  I think the recent gatherings on the Mall demonstrate the wisdom of keeping the Mall open to large-scale political and other demonstrations.  The assemblies may not change minds, policies or electoral results.  But they offer an opportunity for people to assemble in solidarity for large causes and to express hope, frustration, faith, and preferences.
