Fact check: Have there been instances where the National Guard was deployed to restore peace in US cities, and what were the outcomes?

1. Summary of the results

Yes, there have been numerous instances where the National Guard was deployed to restore peace in US cities, with varied outcomes. Historical deployments include the 1967 Detroit riots, the 1992 Rodney King riots in Los Angeles, the 2014 Ferguson protests ^[1], the 1970 Kent State protests, and the 1968 MLK assassination ^[2]. The outcomes varied significantly - some instances resulted in further violence while others helped maintain order ^[1].

More recently, President Trump has deployed the National Guard to Los Angeles and Washington, D.C. ^[3], with some units in Washington now carrying firearms as an escalation of the military deployment ^[4]. Trump has also signed executive orders to expand the National Guard's role in law enforcement, including creating a specialized unit in the D.C. National Guard and establishing a standing quick reaction force for rapid nationwide deployment ^[5].

The current deployments have faced significant opposition from local leaders. NYPD Commissioner Jessica Tisch told Attorney General Pam Bondi that New York City does not need National Guard troops, citing that crime is down ^[6]. Mayors in cities like Chicago and New York City are opposing these deployments ^[3].

2. Missing context/alternative viewpoints

The original question lacks crucial context about the legal challenges and constitutional concerns surrounding National Guard deployments. A federal judge is currently weighing whether the Trump administration violated federal law by deploying the National Guard to Los Angeles ^[7], with the trial raising important questions about the role of the National Guard in domestic law enforcement.

There are significant constitutional and legal concerns that weren't addressed in the original question. Current deployments are being criticized for potentially violating the Posse Comitatus Act and for being an overreach of federal power ^[8]. Local leaders and governors argue these deployments are unconstitutional ^[9].

The question also misses the escalatory nature of recent deployments compared to historical ones. The current Washington D.C. deployment is described as different from past deployments, with potential to escalate tensions ^[8]. The arming of National Guard units represents a significant escalation ^[4].

Political and power dynamics are absent from the original question. Trump is using Los Angeles as a blueprint for deploying the National Guard to other US cities to address crime ^[9], suggesting a systematic approach rather than isolated incident responses.

3. Potential misinformation/bias in the original statement

The original question appears neutral and factual, seeking historical information about National Guard deployments. However, it lacks important framing that could lead to incomplete understanding:

The question doesn't acknowledge the controversial nature of recent deployments, which differ significantly from historical emergency responses. Current deployments are facing legal challenges and are being characterized as potential military occupation of American cities ^[3].

The phrasing "restore peace" could be seen as presuming the deployments were necessary or effective, when the sources indicate mixed outcomes and significant opposition from local authorities who argue they are unnecessary ^[6].

The question doesn't distinguish between emergency response deployments (like riots or natural disasters) versus proactive law enforcement deployments, which represent different uses of military power and have different legal and constitutional implications.
