I've made something out of nothing (or very little). That something is rubbish...
The sensitive topic that is gun laws has resurfaced in America after a series of mass school shootings. At the forehead of the debate is the proposed solution to arm teachers with guns, to which Brooke Jones vehemently disagrees and thus calls for the "president and members of Congress' to think again.
Jones uses logic as her weapon of choice to assert that the responsibility of keeping children safe shouldn't be handed to teachers, via them being armed. By suggesting a series of realistic hypothetical situations, and phrasing them as rhetorical questions, American readers are challenged to reconsider their previous preconceived notions. The repetition of questions also puts emphasis on what Jones is trying to convey, by getting the readers to think on it. The incredulous tone that she uses, and her choice words such as "imbecility" would also make readers feel ashamed, and obliged to agree by default.
Switching to a more passionate tone, Jones urges the audience to consider the burden that's already placed on a teacher's shoulders. The repetition of the word we acts to make the audience feel included, thereby also urging them to sympathise with her. She also juxtaposes the idea of a "committed", "[nurturing]" and "[helpful]" teacher to support the previous idea that no teacher would risk "killing a student, friendly fire or otherwise", in order to make the proposed law seem even more farfetched.
