[1] Kamran Akhtar was one busy tourist. A dam, transit systems, banks. Hmmm. I guess the folks back home wanted to see some infrastructure. From [2] CNN, with thanks to Jeffrey Imm:

(CNN) -- A Pakistani citizen who was arrested while videotaping buildings in Charlotte, North Carolina, was charged with federal immigration violations, authorities announced Tuesday.

Kamran Shaikh -- also known as Kamran Akhtar -- was carrying videotapes of other Southern cities, according to an affidavit signed by U.S. Immigrations and Customs agent John Sherrill.

Those videos included images of Mansfield Dam in Austin, Texas; the MARTA transit system in Atlanta, Georgia; the Downtown Transit Center and Downtown Metro Trolley in Houston, Texas; and trolley cars in Dallas and New Orleans, Louisiana, the affidavit said.
