One morning a police officer and an attorney come by your office to discuss a client who owns a restaurant. They have evidence that the buyer is stealing from your client and want to talk about the internal control environment. You call your client, who says it is fine to discuss these matters. After a brief discussion of the internal control, they ask for copies of canceled checks so they can compare signatures. They also ask for copies of your clients personal and corporate tax returns. How would you respond to: a. discussing the internal control environment with them? b. providing copies of canceled checks? c. giving them copies of the tax returns?
