"Closing the border" isn't a realistic option. We are a country that does business. We can't do business if our doors are locked shut.

The US-Mexico border spans several states... so unless we station an armed guard every 50 feet along the border and stop (and thoroughly check) every vehicle (car, truck, or train) crossing the border, then there will always be meth (and whatever else you can imagine) coming into the US.

so should we close the border to missouri too? because that's the meth capital of the world
