Josephine Shaik, executive director of the Texas chapter of CAIR, which had been working to make sure that Muslims were not seen as a problem in Texas, said that a state police officer went to the mosque a few weeks ago to tell them that she had made an error and had called the wrong address for the mosque or asked him to change that address. Shaj said he didn’t know that until Wednesday, when the mosque posted on Facebook that the original address was correct and he had mistakenly answered the door.

The mosque says his address was right. And an investigation by the law enforcement official who made the mistake says his error didn’t prevent him from using his police training to make an arrest about four years ago.

That informant, said Shaj, was not the name of the individual who later had to be arrested.

According to documents obtained in a federal lawsuit filed by the FBI, though, the informant told him that the wrong address was the one he believed to be used by Hammam. He indicated, the documents said, “that when he searched
