COBB v. the STATE., 348 Ga. App. 210

Background

Cobb, an inmate at Hays State Prison, was tried with co-defendants for injuries to Officer Schrader during a large dining-hall riot; Schrader identified Cobb from photos as one of his attackers.
Evidence included corrections officers’ testimony, inmate Joshua Perry’s testimony that Cobb was lying on the floor during the incident, and that Schrader suffered serious injuries including concussion and stab wounds.
Cobb was convicted by a jury of aggravated assault, one count of riot in a penal institution, and one count of obstruction of an officer; sentenced to consecutive prison terms.
Cobb moved for a new trial alleging ineffective assistance of trial counsel for (1) failing to call inmate Keith Dixon (who would say Dixon, not Cobb, inflicted injuries) and (2) failing to call an eyewitness-identification expert.
At the motion hearing Dixon testified he struck Schrader with a cane and that Cobb was not involved; an eyewitness-identification expert testified generally about factors increasing misidentification but did not opine that the identification here was unreliable.
The trial court denied the motion; the Court of Appeals affirmed, finding no deficient performance or Strickland prejudice from counsel’s omissions.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Was counsel ineffective for not calling inmate Keith Dixon?	Cobb: Dixon would identify himself as the attacker and exculpate Cobb.	State: Similar exculpatory evidence (Joshua Perry) was presented; Dixon’s testimony would be cumulative and did not explain the metal-weapon attack.	No prejudice; omission was cumulative and did not create reasonable probability of different outcome.
Was counsel ineffective for not calling an eyewitness-identification expert?	Cobb: Expert would show high risk of misidentification given chaotic, stressful riot conditions.	State: Counsel pursued a strategy undermining identification through cross-exam, officer inconsistencies, and Perry’s testimony; expert testimony was not necessary or per se required.	No deficient performance; failure to call expert was a reasonable strategic choice and not per se unreasonable.
Did counsel’s omissions cumulatively prejudice Cobb?	Cobb: Combined errors created reasonable probability of different verdict.	State: No errors established (or no prejudice from any errors), so cumulative claim fails.	No — cumulative effect irrelevant where no proven errors causing prejudice.
Was identification of Cobb by Schrader unreliable such that counsel’s performance was constitutionally deficient?	Cobb: Schrader’s identification occurred late, after inconsistent statements; expert would have shown factors undermining reliability.	State: Schrader was familiar with Cobb, identified him from photos, and counsel highlighted inconsistencies at trial.	Court: Identification issues were addressed by counsel’s strategy; expert would not have been decisive and failure to call one was not objectively unreasonable.
