The government and politicians have been claiming 11-12 million for decades. Yet we see the infestation everywhere. The 30-60 million estimate is more realistic. And the 800K misses the 4-5 million illegal family members. All-in-all, very staggering numbers.
How many can be reasonably expected to be handled per year?
How many employees does DHS have?
How many deportations can each handle?
There is no solution except a wall to cut the inflow.
