A federal judge on Wednesday threw out a civil rights case against an Alabama police officer accused of using excessive force on an Indian man.

U.S. District Judge Madeline Haikala granted a motion to acquit Madison police officer Eric Parker after his two previous trials ended in hung juries.

In her 92-page opinion, Haikala said evidence that was presented during Parker's two trials didn't eliminate reasonable doubt that Parker was guilty of a crime.

“The Court has no reason to expect a different result in a subsequent trial given the totality of the evidence that the parties have provided,” Haikala wrote.

While he was out for a walk in his new neighborhood in February, Sureshbhai Patel was stopped by two Madison police officers who said they were responding to a suspicious person call.

When the officers began to question him, Patel said “no English” and “India” as he tried to point to his son’s house and repeated the house number.

Parker slammed the 58-year-old Patel down face first during a suspicious person investigation in February in a Huntsville suburb. The incident was recorded on cameras inside patrol vehicles and Patel was injured in the takedown.

Parker has testified that Patel tried to pull away from him, indicating he may have been up to no good.

Patel has said through an interpreter that he doesn't speak English and couldn't understand officers' orders.

Haikala said in her opinion that based on his training, Parker had to consider that Patel might have said that to evade officers.

Jurors watched police video that shows an officer knocking Patel's legs out from under him and pushing him face-first to the ground. Patel said his arms and legs went numb after the impact, and he could not stand on his own. Parker's colleagues had given conflicting testimony on whether the takedown violated department policy or was necessary.

Haikala said the video didn't account for critical details, including whether Patel put his hands in his pockets before Parker restrained him. Gaps in the evidence were “insurmountable” in the case and it's unlikely that prosecutors would do better in a third or fourth trial, Haikala wrote.

Jurors deliberated for days in both trials and Parker's attorney Robert Tuten said after the second mistrial in November that the length of the jury's discussions highlights the complexity of the case. Tuten has called the case an unfortunate escalation of police tactics.

Assistant U.S. Attorney Robert Posey has said one of the primary difficulties in prosecuting law enforcement in civil rights cases is proving that an officer knew he or she was acting unlawfully.

Alabama Gov. Robert Bentley has apologized to the Indian government for Patel's treatment, calling it a case of excessive force and Patel has filed a civil lawsuit against Parker.
