Two framing points before the substance, because they change how the outcomes read.

First, the two things you've named aren't parallel. The 2020 racial-justice protest wave was a mass mobilization — thousands of events across all 50 states — that generated its own legislative agenda. "Antifa" is a decentralized militant tendency with no organizational structure, and it produced essentially no policy of its own. Its tangible regulatory footprint is almost entirely as an object of counter-mobilization. Second, the durable outcomes split cleanly into two waves: a 2020–2022 reform wave and a 2023–2026 reversal wave. Most of what was enacted federally has since been undone.

Policing law: substantial state action, near-zero federal durability

The state-level output was real and mostly still on the books. An analysis of NCSL data by the University of Maryland's Howard Center found governors approved nearly 300 police-related bills after Floyd's May 2020 killing, with only five states passing no significant policing changes in that period; California and Virginia each approved more than two dozen. Between May 2020 and May 2021, 24 states restricted or banned chokeholds and neck restraints and 11 states changed no-knock warrant rules. Qualified immunity is the narrow exception rather than the rule: Colorado and New Mexico enacted broad statutory bans, Connecticut narrowed the standard, and New York City created a local cause of action — but the doctrine is largely unchanged nationally, and these look like isolated experiments rather than systemic shift.

Federally, the reform wave produced nothing permanent. The George Floyd Justice in Policing Act passed the House twice and died in the Senate, with qualified immunity as the deal-breaker. Biden's substitute, EO 14074 (May 2022), applied only to federal agencies — DOJ use-of-force revisions, a chokehold/carotid ban, no-knock limits, body-camera policy, and a duty to intervene, plus a National Law Enforcement Accountability Database. Trump rescinded EO 14074 on January 20, 2025, and DOJ decommissioned NLEAD. U.S. Department of JusticeCongress.gov

The consent-decree channel closed too. In May 2025 DOJ moved to dismiss the Minneapolis and Louisville consent decrees and closed investigations into police in Phoenix, Trenton, Memphis, Mount Vernon, Oklahoma City, and the Louisiana State Police. A federal judge dismissed the Louisville agreement on December 31; Minneapolis's was dismissed earlier, though a separate state-level decree remains. CNNyahoo

Prosecutorial accountability, by contrast, held: Derek Chauvin was convicted at the state level and separately pleaded to federal civil-rights charges, and the other three officers were convicted federally. That was a genuine shift in a domain where such prosecutions had historically been rare — but it's case-specific, not structural.

Budgets: cut, then restored above baseline

"Defund" was largely rhetorical in fiscal terms. The 50 largest cities cut 2021 police budgets 5.2% in aggregate — often as part of pandemic austerity — while policing rose slightly as a share of general expenditures, to 13.7%. PolitiFact found that of 21 cities that proposed FY2021 cuts, at least 14 scaled the cuts back before adoption or reversed course the next budget year. Austin, the sharpest case, cut roughly $150M and reversed most of it by 2022. Minneapolis voters rejected the charter amendment replacing the police department in November 2021. BloombergPolitiFact

Counter-mobilization: the largest net regulatory output

This is arguably where the demonstrations produced the most durable new law — against protest. ICNL counts over forty new state laws restricting peaceful assembly since 2017, with a concentrated post-2020 wave. Representative mechanisms: Florida HB 1 (2021) broadened the definition of "riot" and created felony penalties, denied bail until first appearance, and allowed officials to appeal municipal police-budget cuts; Iowa shielded drivers from civil liability for injuring someone unlawfully blocking a road during a protest or riot, and Oklahoma extended organizational liability to entities that "conspire" with riot participants. Several were narrowed or enjoined — Florida's riot definition drew an injunction, and Oklahoma's provisions were narrowed following a Tenth Circuit order — but much survived. ICNL + 3

The antifa-specific action is entirely in this column. On September 22, 2025, Trump signed an executive order designating "Antifa" a domestic terrorist organization and directing agencies to use all applicable authorities to investigate, disrupt, and dismantle its operations and funding, followed by NSPM-7, which directs DOJ, Treasury, and IRS to monitor and act against organizations purportedly linked to political violence or domestic terrorism. Two things to be precise about here: there is no domestic analogue to the FTO/SDGT statutes, so the designation cites no legal basis and functions as a policy directive rather than a designation with direct legal consequences — the practical exposure runs through existing conspiracy, RICO, material-support, and tax-exempt-status authorities. The operative risk is to nonprofits and funders, not to a membership roster that doesn't exist. White House + 2

Corporate and institutional: pledge, underdeliver, retreat

Pledges were enormous and disbursement was not. McKinsey tallied about $340 billion pledged by Fortune 1000 companies between May 2020 and October 2022, but the Washington Post's audit of the 50 most valuable companies found 37 had confirmed disbursing at least $1.7 billion of $49.5 billion pledged, and of the $4.2 billion structured as outright grants, roughly $70 million went to criminal-justice reform — the actual cause of the protests. Most of the headline dollars were lending and investment commitments (JPMorgan's $30B) that would plausibly have been booked anyway. mckinsey + 2

The institutional reversal came fast: SFFA v. Harvard (2023) ended race-conscious admissions, and EO 14173 (January 21, 2025) revoked EO 11246 entirely, ended contractor affirmative-action obligations, and required contractors to certify they operate no DEI programs violating federal anti-discrimination law, with OFCCP ordered to cease all enforcement under 11246. The 1965-era contractor compliance framework is gone. Congress.govU.S. Department of Labor

Costs and opinion

Insured property losses ran in the range of $1–2 billion per Property Claim Services, the costliest civil-disorder event it has tracked since 1950, against $775 million (about $1.42B in 2020 dollars) for the 1992 LA riots. The novel feature for underwriters was geographic breadth — the first civil disturbance to cause substantial property losses across more than one state — which pushed SRCC exposure into renewal pricing and exclusion discussions.

Opinion reverted and then some. Pew: support for BLM peaked at 67% in June 2020, fell to 55% by September 2020, and was 51% by 2023; by the five-year mark, 27% of adults said the demonstrations led to improvements in Black Americans' lives, down from 52% who expected them to in 2020.

What remains genuinely contested

I'd flag three things as unsettled rather than resolved, and you should discount confident claims either way. The 2020 homicide spike's causation — protest-related de-policing versus pandemic disruption, gun sales, and social-service collapse — is disputed; rural areas with no defund movement also saw increases. Whether the state-level use-of-force and decertification statutes actually reduced police killings is not clearly established; the national count of fatal police shootings has not declined meaningfully. And officer attrition and recruiting shortfalls are real but their attribution to protest-driven morale effects versus labor-market conditions is contested.
