What Caused The 2020 Homicide Spike? — Essay · Jun 2022

Summary

Highlights companion defending Scott's thesis that the 2020 homicide spike was caused by the George Floyd protests / depolicing (not guns, pandemic, or weather). The sharp centerpiece is the stocks-vs-flows gun rebuttal: gun STOCK rose only ~2% over trend in 2020, so the gun theory needs a 2% stock increase to cause a 30% homicide rise, with the biggest purchase spikes (March 2020, Jan 2021) causing NO homicide spike, and no matching suicide spike -- implausible. Plus the racial-difference correction, the 'started too early' rolling-average artifact, the depolicing mechanism (Graham's account of why police pull back), the criminology-literature pushback (a PhD candidate's hypothesis-A-vs-B distinction), and the weather/international checks (all four Central American countries DECLINED in 2020).

Why this score

Quality 72 · Strong. Strong: a rigorous, well-argued data companion with the incisive stocks-vs-flows gun rebuttal and disciplined international comparisons; top of the Highlights cohort, held here by its dependence on the parent post and its politically-charged single-thesis defense.

Claude’s paradigm shift 48 · Moderate. Moderate: a companion defending a thesis; the stocks-vs-flows framing is sharp but the substance tracks the parent post.

Real-world impact 2 · Minor. Minor/within-discourse: a crime-causation companion; no material footprint.
