11:32 AM PT -- 11/19 -- Jones' attorney, Michael A. Gottlieb, tells TMZ Sports he does not believe his client committed a crime Wednesday ... saying, "It's not illegal to possess a gun."
Gottlieb says Jones was just trying to get gas ... adding, "I think it's an unfortunate misunderstanding. I'm sure it will be resolved hopefully before court."
10:52 AM PT -- 11/19 -- A 911 caller told cops he was worried Jones was going to seriously hurt somebody prior to his arrest Wednesday morning ... saying the ex-Dolphins star was straight-up "looking like he's about to kill somebody."
It's all in new police audio obtained by TMZ Sports ... in which you can hear a man spell out the scene.
The caller told dispatch, "there's a black man with a gun in his hand walking down the street."
The caller later added, "I don't think he's right in the head right now, man."
The caller described Jones as "a black male with a beard, black shirt, red sneakers. You can't miss him. The gun is -- he's right there with it in his hand. Going down the street with something on his mind."
The caller explained to the officer he was so concerned about the situation, he wasn't going to go remotely near Jones.
"There's a man with a gun looking like he's about to kill somebody," the man said in the call. "Police need to get here quickly."
Reshad Jones -- a former Pro Bowl safety for the Miami Dolphins -- was arrested in Florida on Wednesday after cops say he was illegally carrying a loaded firearm.
According to a police report, obtained by WPLG Local 10, cops made contact with Jones at around 4 a.m. after witnesses say the NFL free agent was walking around Davie, Fla. gas stations carrying a gun.
In the report, officers say when they began questioning the 32-year-old former Miami defensive back ... they noticed the firearm sticking out of his pants.
Cops say Jones told them he did NOT have a concealed weapons permit ... and initially complied with their arrest orders for him to get on the ground.
Officers in the report, though, noted Jones later became combative ... and "appeared to be on the influence of an unknown substance."
Cops in the report also say Jones reeked of booze.
Jones was eventually arrested and booked. Jail records show he's since been released.
Jones had a great career for the Dolphins after being picked by the team in the 5th round of the 2010 NFL Draft. He played in Miami for 10 seasons, starting 113 games and recording 21 interceptions.
Jones was released by the 'Fins after the '19 season ... and he's yet to latch on with another team.
