Another instance of guilt before innocence. I'll chalk this up to the same feeling with pharmacists who require me to sign a federal form when buying a package of Sudafed when I have a held cold.

Because, ya know, about 90% of Americans get a head cold, but only about 1% percent are meth addicts. So punish the 90%. Don't acknowledge that you also need gallons of brake fluid and battery acid for a single batch of meth. And a heck of a lot less than 90% of us are buying those ingredients.
