The Bath School disaster may not be such a good example for opponents of gun control to bring up. The main explosive used by the perpetrator was something called pyrotol. According to Wikipedia: “distribution of pyrotol for farm use was discontinued in 1928” (the following year).
I believe that the surplus supply was used up in 1927/1928. The excess was gone so the need to distribute it was also gone, not the Bath disaster.
I’m suprised after OKC the goobermint didn’t ban rental trucks.
