It appears the explosive devices he had were "electric matches" and his smoke generators contained "Potassium Chlorate". I looked up the electric matches and the ATF has them listed as a class 1.4(Minor explosion hazard). I didn't look up the chlorate. My last order of smokeless powder was labeled as "Explosive C 1.4" That puts it under the same class, but under the propellant category. Though he did get nailed for possessing 3 guns.
The point in fact is his prior felony, and his possession, not what he possessed.
And it brings back a favorite subject of mine- I know quite a few good ol boys who kicked their heels up a mite too high in their yoot (truly there, but for the grace of God, go I) and were hung with a felony conviction... They cannot possess a firearm, nor any sort of explosive, *FOR LIFE*, along with losing the right to vote and etc...
That's damn well wrong. Country folks survive on hunting. especially in hard times. And such a feller, when faced with a stump to pull, is not likely to fail to resort to the thing that works the best for doing it, and can be easily made from things he has laying around... And remits the cost of a backhoe and operator, a cost he likely cannot cover. IOW, of course he is gonna blow the damn thing up.
And along those lines, it is near impossible to live in the country and NOT possess the fixins. So it is always just a matter of desire on the part of the Law, to saunter in at any time and throw his ass back in the hoosegow. And it happens just that way all the dang time.
Another reason for country folks to have a weird love/hate thing going on with the law - Especially the feds, as the local law tends to understand that a feller meant no harm and would look the other way.
