This is a summary report on a sting operation case I worked on as an applied linguist. In it the target was a non-native English speaker with a beginner level of English proficiency. The sting setting was a discount store. The undercover officer attempted to persuade a store employee to buy jugs of alleged stolen liquid detergent for sale in the store.
