Ok but now it's not that they're being followed from the grocery store, it is hypothetical digital profiling that is the problem. Even this is more resource intensive than the direct approach, i.e.: they would have an easier time snatching "random" illegal immigrants by driving up to construction sites and harassing general labourers, or coming in the back door of a restaurant.

If they are able to commit resources to deep surveillance of the entire white population on the off chance of catching someone delivering food to an illegal immigrant, then why would they not commit a drone to follow the individual the whole way to their destination? Again, this surveilled individual apparently knows where they are going "by paper", without GPS, not by memorisation of an address. Why? The story is simply nonsense.
