But somehow, a few dozen Africans not going through Heathrow represents a "flood" and an "invasion".
My son's better at numbers than you guys, and he's only had one year of school so far.
A few dozen? It's thousands. And they are not here for vacation, but to stay forever, because it's virtually impossible to deport these illegals.
The number of arrivals in the entire month of July 2018, across the entire Mediterranean (Spain, Italy Greece) was 450 per day. For the entire year so far it was less than 300 per day. That's a tiny fraction of a percent of the daily international arrivals at Heathrow alone, let alone any other airports.
Those arrivals at Heathrow leave. The immigrants can't meaningfully be deported.
It's like arguing that because the filter pumps don't raise the water level in a pool it's obvious a hose won't, either.
