The only tie in to the Sikh's was that a Sikh company based out of New Mexico had the contract to provide security for the Murrah building. The company was never properly registered with the Oklahoma Secretary of State to do business in Oklahoma. That same unheard of security company has grown since 1995 to provide security at a majority of U.S. federal courthouses. It is simply a side story to the OKC Bombing case since one could say when the bomb exploded, the people being paid to provide security for the building had failed the taxpayers. However, AKAL has since grown to be one of the major contractors for security for the federal government. I only mention the link because that is where the information on Siddiqy and Chafi is.
