Here is a quote from an archived newspaper.
Two dozen armed Negroes entered the state Capitol at noon today and 10 made their way to the back of the Assembly Chamber before they were disarmed and marched away by the state police.
The Assembly was in session at the time and Speaker Pro Tem Carlos Bee ordered the men removed from the chamber.
Outside the chamber, the police took away the weapons. The men argued they could carry the weapons as long as they were not concealed.
Apparently the fact the weapons were not concealed was the reason the men were able to get as far as the Assembly Chamber before they were disarmed.
After the state police questioned the men, they returned the weapons to them because the intruders had broken no law.
Following their release by the state police, the men left the Capitol and rejoined some companions who remained outside during the incident. They then drove off.
