masonic is ignoring the possibility that "gas" talk was figurative. It was reported that Oathkeeper Thomas Edward Caldwell received facebook messages during the insurrection: “Tom all legislators are down in the Tunnels 3floors down,” and “Go through back house chamber doors facing N left down hallway down steps,” and “All members are in the tunnels under capital seal them in. Turn on gas,” according to the FBI.

Perhaps "seal them in, turn on gas" was a figurative way of saying "trap them and kill them". Source: https://www.washingtonpost.com/local/legal-issues/conspiracy...
