A Molotov cocktail thrown into a crowded school room could easily kill and maim as many or more kids than a madman with a firearm that the hoplophobic media invariably describes as an "assault weapon". In the media's dictionary, any firearm more modern than Davie Crockett's flintlock squirrel rifle when used in a crime automatically becomes a dreaded ""assault weapon" that somehow induced it's otherwise sane and law abiding possessor to open fire on innocent men, women, and children. How stupid do they think we are?
On second thought, the majority of "us" probably are as stupid as they think since an unreasoning fear of firearms has been drilled into "us" for decades.

The Bath School disaster refers to the series of violent attacks perpetrated by Andrew Kehoe on May 18, 1927, in Bath Township, Michigan, that killed 38 elementary school children and six adults in total, and injured at least 58 other people.[Note 1] Kehoe first killed his wife, fire-bombed his farm and set off a major explosion in the Bath Consolidated School, before committing suicide by detonating a final explosion in his truck. It is the deadliest mass murder in a school in United States history
