Criminals will also always be able to get explosives, or even create them themselves. And if they can't create them themselves, they use airplanes. Is that the reason and excuse to legalize explosives and make them available for the average Joe? Perhaps at Walmart?
Tannerite is a legal binary explosive you can purchess straight from the manufacture, no special requirements.
For anything else, you need to get an FEL, link.
