A plausible account for the dramatic 2020 increase in urban shootings is a rapid change in policing practice and deterrence following late‑May protests (e.g., after George Floyd’s death), rather than seasonal weather, lockdowns, or gun purchases alone. That hypothesis stresses timing (surge beginning the last week of May), concentration (large cities, shootings vs. other street crime), and mechanism (reduced proactive enforcement and deterrence), and is empirically testable with arrest, deployment, and incident‑level data.
— If true, it changes policy remedies from only addressing gun access or economic conditions to recalibrating urban policing tactics, deployment strategies, and accountability frameworks in ways that affect minority‑neighborhood safety.

Singal’s article connects individual cooperation with police (or lack thereof) to downstream lethal outcomes: the Post source’s reluctance to ‘put another black man in jail’ is presented as a micro‑mechanism that can reduce police leverage and thus public safety—this maps to the existing claim that changes in policing and community–police interaction materially affect homicide and public‑safety trends.

While the article is anecdotal rather than statistical, it ties a string of law‑enforcement and judicial leniencies (releases, short psych evals, no‑bail decisions, victims declining to cooperate) to rising lethal risk — a microcase that connects to the broader debate about how changes in policing/prosecution practice affect violent crime.

The article advances the argument that failing to provide policing (a 'pullback' or reluctance to enforce) causally enabled higher homicide risk for marginalized communities and points to improved outcomes when policing improves — e.g., citing Baltimore's clearance‑rate rise from ~40% (2020) to 68% (2024) — which directly maps onto the existing idea that policing withdrawal contributed to homicide increases.

The article recounts the 2020–21 period of street‑mob disorder, rising murders and traffic fatalities, and contrasts that spike with the later fall in crime after a law‑and‑order shift under Mayor Eric Adams — directly invoking the template that policing changes (pullbacks or restorations) drove the 2020 crime surge and its recovery.

While the author does not claim a specific cause, the piece highlights the 2020 spike in homicide rates and emphasizes homicide as a reliable metric — supplying the empirical foundation that underpins debates about whether policing changes contributed to the 2020 increase.

The article's analysis of Mayor Mamdani's Office of Community Safety — arguing that mental-health responders won't replace the need for sworn officers and that many calls still require police presence — ties into debates about the consequences of reducing traditional policing capacity and the limits of substitution with non‑police responders.

Kling links reduced school‑and‑street police presence and 'anti‑police' policies to a post‑2020 youth crime wave in Montgomery County, illustrating the existing pattern that policing decisions after 2020 reverberate in local public‑safety and schooling outcomes.

Smith argues that progressive tolerance of public disorder, reduced policing budgets, and progressive prosecutors (naming Chesa Boudin) damaged San Francisco's livability; that directly connects to the existing claim that reductions in policing/enforcement contributed materially to urban crime rises and weakened urban recovery.

Smith invokes depolicing and decarceration debates as partial contributors to America’s high violence, engaging the same causal thread covered by the existing hypothesis that changes in policing practice helped drive recent homicide trends.

While not directly about the 2020 spike, the article’s central claim (that protest dynamics alter policing latitude and outcomes) maps to the broader pattern that changes in policing posture and public‑order signals can produce measurable shifts in lethal violence and enforcement outcomes.

The podcast advances the Manhattan Institute’s public‑order argument (Broken Windows, deterrence) and critiques progressive policing. That directly connects to the existing idea that changes in policing practice/deterrence explain recent homicide trends; the actor (Heather Mac Donald) is a prominent proponent of this explanation and the episode explicitly links mayoral policy choices to daily safety outcomes.

Yglesias cites the 2020 spike and the subsequent 30‑month decline while noting mechanisms (detective time, patrol availability) that align with the existing idea that changes in policing practices and deterrence plausibly drove the initial rise and the later fall; both pieces emphasize timing, city‑level deployment, and the need for detailed deployment/arrest data to test causality.

Paul Cassell law‑review synthesis cited in the article; Gun Violence Archive national counts (~19,000 gun deaths in 2020); city examples (Minneapolis +95% May–Aug, Chicago doubling in July, NYC 50% homicide increase) and the surge’s start date (last week of May, post‑George Floyd).

The article analyzes demographic and geographic correlates of the 2020 homicide increase and engages the same causal debate: whether changes in policing and law‑enforcement behavior explain the spike. Although the brief doesn't solely attribute the rise to policing, it tests alternative drivers (COVID deaths, gun sales) and reports county heterogeneity that is consistent with a policing‑related component.
