It looks like there was some backlash, because they producers released an official apology. Seriously, they make it sound like they were visiting China, not Kentucky!
We apologize to any viewers who were offended by the misinterpretation of the contestant's comment to "be careful" upon completion of his audition in Louisville, KY. Our visits to audition cities are relatively brief and sometimes regional greetings and salutations are lost in translation. We had not heard that phrase from any other contestants during the day, so it took everyone by surprise. We now know better and look forward to visiting Louisville again someday.
