I bought some Chapati flour last week from the supermarket

Is there any restriction or tracking on the purchase Esbit tablets considering Hexamine is one of the primary ingredients for making RDX based plastic explosive?

It sounds like the 'Terrorists targeting G8/G20 summit' story with a fertilizer bomb is just a way of keeping the rentamob crowd away although this will probably disappoint the members of the local constabulary as they listen to this on their MP3 players
