The following was posted to a Houston Chronicle blog:
The FBI and Federal Homeland Security investigators are investigating an incident in downtown San Antonio this morning, after two men identified as "French Moroccans' were arrested inside the old Bexar County Courthouse, and a third man was found outside the building in a van, 1200 WOAI news reports. Police now tell 120 WOAI's Michael Board on the scene that photographs of 'infrastructure' including courthouses and water systems from around the country, have been found inside the men's van. One sergeant says the three men were apparently traveling the country photographing infrastructure. San Antonio is home to three major military bases, and officials have notified them of the incident, and have told them to be on the lookout for any suspicious activity and vehicles.
WOAI radio appears to have revised the story to now read, in part:
Inside the van, officials say they found "photographs of infrastructure" including photos of shopping malls, water systems, courthouses and other public buildings which they say were taken in cities nationwide. "They got travel documents, parking passes, they have been all over the country," one law enforcement officials who asked not to be identified told 1200 WOAI's Michael Board on the scene. "A lot of photographic equipment, a lot of documentation equipment inside their vehicle."
