Mitt Romney denies knowledge of ALEINS.?

Does Mitt Romney have Secrect Service protection. Because the slogan of the Secret Service is to walk up to a subject of interest and ask them "Have you lived here ALL of your life?" and if the subject gives any sort of reaction involving a discomfort or lie, the subject is escorted away to a secure area and their residence is promptly searched without a warrant. So, is Mitt Romney lying?
