It seems silly to me. Acetone comes in 8–12 oz bottles. You can go to the hardware store and get it by the gallon. Does it make sense to card people in one place and not the other?
But consider your average store – drug store, hardware, even Target or K-mart. Thousands of items in any given store could be used to make explosives, or mix drugs, or do some nefarious thing or another. Just yesterday, I was at Home Depot and bought some paint stripper/paint remover. That’s some high percentage of alcohol and is explosive. They didn’t card me on the way out.
These sort of gestures are silly. Eventually they will be worried about every single thing you buy and some computer will store that information. Then we will have completed the state control of our lives in a way that the NSA can only dream of.
This is a dumb idea – it is theater, and accomplished nothing at all.
