Leonides Velazquez v. City of Camden and Officer Alexis Ramos, 146 A.3d 681

Velazquez was shot twice in the torso by Camden police Officer Alexis Ramos after Ramos responded (on his own initiative) to a late-night domestic disturbance; witnesses disputed whether Velazquez held a small palm-sized rock or a large 18–29 inch paver raised over his head.
Ramos testified he perceived a large, deadly threat and fired; defense expert cited tunnel vision and stress to explain Ramos' perception.
Plaintiff sued under the New Jersey Civil Rights Act and also asserted Monell claims against the City of Camden; jury returned no-cause verdict for defendants.
At trial the court allowed an assistant prosecutor to testify only that Ramos was not criminally prosecuted, but excluded the prosecutor’s reasons; the court also barred any reference to Ramos’ psychological/mental-health records.
The Appellate Division held both rulings prejudiced plaintiff: the prosecutor’s testimony improperly bolstered Ramos’ credibility and the mental-health evidence was admissible to impeach Ramos’ perceptions and credibility.
The court reversed and remanded for a new trial as to both Ramos and the City, concluding the errors were not harmless given the close credibility dispute and Monell claims implicated by the mental-health evidence.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Admissibility of assistant prosecutor's testimony that Ramos was not criminally prosecuted	Testimony was inadmissible lay opinion/non- evidentiary and highly prejudicial	Prosecutor’s testimony was proper rebuttal/opening invited response; relevant to weight of evidence	Reversed: Evidence of non-prosecution inadmissible here; it improperly bolstered defendant and risked unjust result
Exclusion of Ramos' mental-health records	Records relevant to impeach Ramos' perceptions/credibility (nightmares, concentration, prior light duty)	Mental-health evidence irrelevant because excessive-force claim is judged objectively (subjective state of mind immaterial)	Reversed: Mental-health evidence admissible to challenge officer’s ability to perceive and credibility; exclusion prejudiced plaintiff and Monell claim
Application of objective-reasonableness standard	Does not bar probing officer’s perceptual deficits; plaintiff may use extrinsic evidence to test credibility	Objective standard renders officer’s subjective state irrelevant	Court: Objective standard governs legal test but does not immunize officer from credibility impeachment; perception evidence is relevant
Prejudicial effect and harmless-error analysis	Combined evidentiary rulings were not harmless given close credibility fight	Error was harmless or cured by instructions	Court: Errors were clearly capable of producing unjust result; reversal required
