Jason’s prediction was that the week immediately following election night 2020 could be “incredibly violent” in the U.S.

What actually happened between roughly November 4–11, 2020:

• Election night itself saw only scattered, mostly peaceful protests. Associated Press coverage noted “scattered protests” but “no signs of widespread unrest or violence” as of election night and the immediate overnight period; demonstrations in cities like Seattle and New York were largely peaceful, with no broad breakdown in public order.

• In the following days there were numerous demonstrations, but only localized violence. Monitoring by groups like Civicus and various news outlets describes marches and rallies in many cities (Washington, New York, Philadelphia, Portland, Phoenix, Detroit, etc.), including “Count Every Vote” and “Stop the Steal” events. Some of these led to clashes and arrests — e.g., New York police arrested around 50 protesters; Portland police declared a riot and arrested 11; Minneapolis saw protests blocking roads and confrontations with police — but reports emphasize that most protests remained peaceful and incidents were geographically limited.

• Minneapolis is a good example of the pattern: intense but not mass-casualty violence. On election night, protesters in Minneapolis caused some property damage and shot fireworks at officers, leading to 14 arrests for alleged rioting and assault. The next day, a large march entered Interstate 94; police used tear gas and mass-arrested 646 people for unlawful assembly and related offenses, with a few individual assault charges (e.g., pointing a laser at an officer, kicking an officer). These were serious confrontations but involved very few serious injuries and no deaths. (en.wikipedia.org)
• Systematic data show most protest activity in this period was non‑violent. The ACLED/US Crisis Monitor weekly overview for November 1–7, 2020 documents an 80% jump in demonstrations around the election, but treats them largely as protests and intimidation/threat incidents rather than widespread lethal violence. (bridgingdivides.princeton.edu) Aggregated ACLED-based analyses of the broader May 24–November 28, 2020 period record 17,946 demonstration events, of which only about 4% involved violence and 3.5% involved police intervention, with 85 total fatalities linked to all political violence and demonstrations nationally across six months — indicating that, while tensions were high, outright violent events remained a small minority and there is no sign of a unique nationwide spike in killings or extreme bloodshed during the immediate post‑election week.

• Later, much more severe political violence did occur—but outside the predicted week. The most dramatic election-related violence, the January 6, 2021 attack on the U.S. Capitol, came more than two months after election night and is widely treated as the culmination of a prolonged contest over the election results, not something confined to November 4–11. (en.wikipedia.org)

Overall, the United States in the week after election night 2020 saw widespread protests and some localized riots, arrests, and minor clashes, but not the kind of pervasive, high‑casualty, or structurally destabilizing political violence that would reasonably be described as an “incredibly violent” week nationwide. Fears of mass violence and intimidation around the election were widely reported beforehand, but post‑election assessments and data agree that these worst‑case scenarios did not materialize at scale.

Because the scenario Jason warned about — an immediately ensuing incredibly violent week — largely did not occur, this prediction is best scored as wrong.
