A nation wide blanket restriction is a dumb way to go about any attempt at neighborhood safety. It is a best indirect. But again, making meth in a home lab hasn't been economically viable for the better part of 10 years now, so why is the restriction still in place?
I just don’t see how selling snake oil made my neighborhood safer. Like I don’t see how those two things are connected at all other than through motivated reasoning. Not to mention anybody can still walk into my local Walgreens at 4 A.M. with a mask and a tire iron and take as much Sudafed as they’d like.
