the defense that he has already accepted the qualifications of the witness." "I am not attempting to impugn the qualifications of the witness," I snapped. Judge Lapworth frowned at Thursby. "Are you making an objection, Mr. District Attorney?" Thursby pursed his lips, said, "No, Your Honor," and sat down. "Proceed with the cross-examination," said the judge. "Mr. Thompson," I said, "you have testified that you examined the table at the Golden Casino for such devices and found none. Is that right?" "That's right," he said positively. "Have you seen the device labeled People's Exhibit A, which was found by the officers on the person of the defendant?" "Well ... yes. I have." "Have you examined this device?" Thursby was on his feet. "Objection, Your Honor! This material was not brought out in direct examination!" "Sustained," said Judge Lapworth. "Very well, Your Honor," I said. Then I turned back to Thompson. "As an expert in this field, Mr. Thompson, you have examined many different devices for cheating gambling equipment, haven't you?" "Yes, I have." "How many, would you say?" "Oh ... several hundred." "Several hundred different types?" "No. Several hundred individual devices. Most of them are just variations of two or three basic types." "And you are familiar with the function of these basic types and their variations?" "I am."
