The suggestion that there are no unannounced inspections any more causes some alarm. Your report will show, if it's an analysis of what has actually taken place since April 2013, which ones had no announcement.
We also note that in the definition of surveillance—this goes back to Ms. Chow's suggestion that there have been 13,664 inspections—an inspection or a surveillance includes an e-mail. If there were 13,663 e-mails and one inspection, we wouldn't know.
I don't consider an e-mail to a company to be surveillance, really, but your own documents indicate that's what that is. Can you at least break that out for us so that we can know where there's been a physical presence, as in surveillance, as opposed to just an e-mail from the department or an inspector to a company?
