Purchases of high-test peroxide might be suspcious. But low-test peroxide and the other materials would not be. The vast majority of purchases would be innocent. Going after innocent people is unfair, more likely to result in false prosecutions, and inefficient from a law-enforcement point of view. Trying to tace all buyers of acetone is like the no-fly list. It creates so many false positives that it is statistically likely to help criminals escape the net.

I am sceptical about claims that this was the same process as the London bombing. At the time, the London bombers were said to have used hexamine (camping stove fuel tablets) and peroxide. MSM reports seem to make no distinction between any of these compounds. Instead, they just say they are “the same” to imply a linkage, somethng that I very much doubt is there.

Also, the claim that Zazi had a bomb recipe traceable to Pakistan is suspect. Why would he. if he were the real deal? All he had to do was to google the compounds, as I just did, or even “bomb making” and he would get all he needed.

If my amateurish suspicions about the suitability of the chemicals are correct, a provocateur could tell them to purchase these things and maybe even mix them without too much fear of having a real bomb on his hands.
