Still don't think we need a wall?

[KUSA]

I have an idea: hear me out on this one.

There are about 270 million privately-owned guns in the US.

Let's assume 1) each of these guns weighs approximately 8 lbs (tiny handguns will be balanced out by the occasional bfg) and 2) that the mass is half steel and half aluminum (I know this is wildly imprecise; but stay with me, this is a back-of-the-napkin calculation).

Aluminum is about 170 lbs per cubic foot, and steel is about 480 lbs per cubic foot. This averages out to 325 lbs per cubic foot of gun.

We have 270 million guns, and if each weighs 8 lbs, we have 2,160,000,000 lbs of privately-owned gun in the US. At 325 lbs per cubic foot, this works out to just over 6,646,000 cubic feet of gun. We're not counting ammo, by the way.

The US-Mexico border is 1,954 miles long. The United States Border Patrol has control over 700 of these miles, so we'll only focus on the 1,250 miles they do not have under their control. This may disappoint purists, alas. By now, of course, you see where this is going.

1,250 miles * 5,280 feet per mile = 6,600,000 feet of unsecured US-Mexican border. This means there is almost exactly one cubic foot of gun for every unsecured foot of US-Mexico border.

So, the upshot:

If we melt down all of the privately owned guns in the USA, we can use them to make a US-Mexico border wall of solid metal, 8 feet in height and 1.5 inches thick.

Final conclusion: The US can have its guns, or it can have its wall... but not both.

you can drop the Nobel Peace Prize on the porch out back.

False dichotomy. You failed.
