@farmerman,
People are careless and no matter what system you had in placed it can be gotten around hell he could had gotten the job of keeping track of those materials as I question if that job would be done at any higher level then a graduate student.
Next people with one hell less knowledge and education then this shooter had produced very very large explosions so your claims that it is a hard thing to do seems on it face silly.
A farm boy level a large building for example and gun power confine in the proper manner work just fine if you are force to go low tech.

Chlorate impact explosive. Meth manufactured by the “red phosphorous method” already has red phosphorous which has probably been obtained from match sticks or highway flares. If the red phosphorous is mixed with potassium chlorate to which a small amount of sulfur is added, a dangerous explosive is formed. The potassium chlorate is first ground and mixed with a small amount of sulfur and then mixed with water. Red phosphorous is then added. When the mixture dries, it is extremely shock sensitive. Sodium chlorate might be used instead of potassium chlorate.
Drug raid tip-off: red phosphorous filter stains from meth manufacturing, and/or broken match sticks/flares; sulfur; any chemical containing chlorates such as potassium chlorate; suspicious powders or crystals scattered about the floor or at various locations.
Nitrogen triiodide. Ammonium hydroxide (ammonia water) is added to iodine crystals and allowed to react. The nitrogen triiodide crystals are allowed to form and settle. Iodine crystals is also an ingredient in meth manufacture by the red phosphorous method. The nitrogen triiodide crystals when dried are extremely shock sensitive Even sunlight or the slightest shock may set it off. The crystals might be dispersed wet and allowed to dry at the time of the raid.
Drug raid tip-off: dark red-brown iodine stains or crystals; smell of ammonia
Nitrogen trichloride. There are several ways of manufacturing this dangerous compound. Ammonium hydroxide or anhydrous ammonia which is also used to manufacture meth is a starting material for this explosive. One method is to place a saturated ammonium chloride solution in an ice bath and connect two carbon or lead rods (from a battery) placed in the solution to a battery charger. The nitrogen trichloride forms as a yellow oil under electrolysis of this solution. Another method is to slowly bubble chlorine (generated from a bleach solution or swimming pool chemicals) into a ammonium nitrate or ammonium sulfate fertilizer. The final yellow oil is highly unstable and can explode on contact with almost any organic material or if heated. It is very shock sensitive.
Drug raid tip-off: Fertilizers with high ammonium contact; or ammonium hydroxide; hydrochloric acid; battery charger; chlorine/ammonia odors; yellow oil.
Acetone peroxide. Also called triacetone peroxide, tricycloacetone peroxide, or TATP. There are three forms of acetone peroxide with varying degrees of stability depending how it is made. When it explodes almost all of the energy is directed towards the blast and very little appears as heat. The explosive power is similar to TNT on a mass basis. Basically, a solution of 30% hydrogen peroxide is mixed with acetone and cooled to 5oC. A small amount of sulfuric acid (Sp. Grav. 1.84) is added while stirring. The mixture is allowed to sit, allowing acetone peroxide crystals to settle out. The crystals are filtered and washed with water or a baking soda solution. This procedure should produce mostly the cyclic form (tricycloacetone peroxide). The material has a shelf life of about 10 days. Its half life is about a month or two. A more dilute solution of hydrogen peroxide (e.g. 3%) or battery acid may be used but yields will be much less, and the monomeric form of the explosive will dominate. If the reaction is above 10oC, the unstable dicycloacetone peroxide will be formed (which can spontaneously explode). There are procedures available on the Internet for concentrating the hydrogen peroxide. Battery acid can be concentrated by boiling until white fumes begin to occur. At least 2 grams of the material must be present for acetone peroxide to detonate in an unconfined space, but someone walking on a crystals spilled on the floor can still be injured. One crystal decomposing violently can set off all the others on the floor. Trace amounts of metals (rust, iron, copper, etc. can cause the hydrogen peroxide to decompose violently. The shelf life of the explosive may be extended by dissolving in an organic solvent. If stored in a container with a screw cap, unscrewing the cap can cause the peroxide crystals to detonate. More technical details in Journal of the American Chemical Society volume 81, page 6261 ff, (1959).
Drug raid tip-off: Acetone, sulfuric acid or battery acid, and/or hydrochloric acid are commonly found at meth labs. The tip-off is also finding hydrogen peroxide, especially the more concentrated solution.
Methyl ethyl ketone peroxide. Similar to hydrogen peroxide except methyl ethyl ketone is used instead of acetone.
If any oxidizers are seen during a meth lab raid, the possibility that explosive materials are also being produced should be seriously considered.
HMTD. Also called Hexamethylenetriperoxidediamine. The raw ingredients are 27 or 30% hydrogen peroxide, powdered hexamine, and citric acid. The hexamine might be obtained from an army surplus stores as a solid fuel tablet used for outdoor camping, and might go by the name “urotropine’ or “hexamethylenetetramine”. Citric acid might be obtained from a food or drug store. The hexamine is crushed, mixed in with the hydrogen peroxide solution, and citric acid added while keeping the temperature below 10 C. The precipitate formed is filtered, washed, and allowed to dry. The dried precipitate is extremely shock sensitive and can detonate even in sunlight. The moist crystals might be spread around just before a drug raid. [see

Drug raid tip-off: army surplus hexamine fuel tablets, hydrogen peroxide (might be sold as hair bleach), citric acid (might be sold as sour salt).
Pipe bomb. Black powder is a favorite of pipe bomb users. Ingredients of black powder include charcoal, powdered sulfur, and potassium nitrate (sodium nitrate might be substituted). Alcohol (rubbing alcohol) might also be used in the manufacture.

Acetone peroxide (left) is a white, crystalline powder with a distinctive acrid odor. Three forms are commonly formed, the monomer, dimer, and trimer. The recipe described above (use concentrated chemicals, 5oC) favors the trimer form, also called tricyclic acetone peroxide, or TCAP). The other forms are less stable. TCAP will slowly sublime at room temperature. All forms are shock sensitive.

Of course, many of the chemicals which can also be used to make home-made explosives are found in ordinary homes. They are used for legitimate purposes such as furniture restoration, as disinfectants, scale removers, automotive finish restoration projects, solvents for brush cleaning and varnish thinners.
