Weapons certainly don't belong in a Courthouse. However, it happens anyway and shootings have occurred. Only law officers should have guns in Courthouses, and Barbecan portals are the answer. Most government buildings have access via key card. However, the DC Navy Yard shooting at a government office building proves that solution is not effective. Even the DHS (Department of Homeland Security) office buildings in downtown DC are protected only by metal detection arches and an X-ray machine. A determined attacker can easily shoot their way in and wreak havoc on whoever they desire.
