One of the great beauties of having an ahistorical public is you can get lots of shock value out of what is essentially a factual retelling of where we come from.
The main bridges across the Thames in London used to be garnished with the heads of executed criminals - or those deemed criminal by the ruling body of lawgivers - decapitated, then impaled on pikes and dipped in tar to preserve them against the elements, left there as warning and sign.
Did it work?
Define work.
Harsh measures are often necessary.
What we should do about the urgent problem of massive illegal immigration through our porous southern border is encourage all those would-be armed and willing posse comitatus/vigilantes to head south and man the frontier.
And shoot on sight anyone - man woman or child - entering the US illegally.
Then we can make a fence out of their corpses. Right down the borderline.
A Not-So-Running Fence.
Dead bodies every yard, or meter, will give us over a thousand miles of fence per million dead illegals.
Add another half million and we can cover the distance between San Diego and Brownsville, give or take a few hundred dead "immigrants".
This will be effective in its inception - during the initial gathering of materials, the most active part of its construction - and will work equally well for many years to come, as the bones of these criminals whiten in the dry desert air, a grim and silent warning to would-be opportunists who should have stayed home.
