One case, handled by the Central Division in Chicago, we may call the Otero case. Word came from El Paso that a certain prominent Mexican, a revolutionary and political leader with aspirations for a very high office in that republic, had come into the United States and was headed north, probably for Chicago. Nothing was known about him and his purpose excepting that his name was given. The League at once began making inquiries about Senor Otero. It was found that he was traveling in a special car. Obviously, therefore, he was a man of money. Ergo, he would go to a good hotel, and he probably would make a reservation in advance. Inquiries were made by telephone at all the leading hotels in Chicago, which in practically all cases were members of the American Protective League. Senor Otero was found to have reserved a large suite at the Blackstone, and had made the time of his arrival known. From that time on, he was in the hands of the American Protective League, although he never knew it. The boy who took his bag at the door was an A. P. L. operative, the bellhop who responded to his summons was an A. P. L. operative, his waiter at table was A. P. L., his night taxicab driver was A. P. L. In fact, the A. P. L. put Senor Otero to bed and woke him up in the morning, followed his activities during the day and knew what he was doing all night. It was not discovered that he was engaged in any plot against the peace of the United States, but was apparently active in the more pleasant task of spending some money he had gotten hold of in Mexico. If relatives or friends of the Senor Otero would be pleased to know how he spent it, the nature of his associations in Chicago by day—or night—and if they can persuade the Department of Justice to advise them, they can find the entire record of his stay in Chicago. Had he been engaged in any suspicious acts against this country, his return to Mexico might not have been so peaceful.
