Deport a million illegals a year?

There approximately 20-40 million illegal aliens in the USA (depending on source). Basic math dictates this whole deportation mission will take 20-40 years (2,740 per day), assuming the objective's goal is reached annually.

While deportations were ramped up prior to this bill, it was odd how low the deportation number reports were (as of 6 months). Almost like it was on purpose to justify an action.
