Mark Hughes of Dallas was misidentified as a suspect after terrorists killed 5 Dallas police officers and wounded 6 more at a peaceful protest on Thursday.
A social media photo shows Hughes wearing a camouflage shirt and carrying a long rifle at the protest march in downtown Dallas.
Dallas police officers monitoring social media spotted Hughes' photo and immediately identified him as a suspect.
Video posted on social media shows Hughes calmly approaching an officer who confiscated his weapon and took him down to the police precinct for questioning.
Hughes was later released from custody but he had harsh words for the Dallas PD.
In an interview with a CBS News affiliate, Hughes said he was interrogated by police for 30 minutes. He said police interrogators lied to him, saying they had video of him firing his weapon.
Hughes said the cops told him they also had witnesses who saw him shooting a gun.
Hughes said he wasn't aware he was a suspect until he received a phone call that his face was plastered on the natiomal news as a suspect.
"Immediately I flagged down a police officer," he said.
Hughes said he was "laughing and joking with police officers" prior to the sniper attack.
Hughes' brother received death threats on social media after he was misidentified as a suspect.
When asked if police apologized to him, Hughes said no. He said he's not satisfied with an apology from police.
"At the end of the day, the system was trying to get me," he said.
