Jeezy ... Illegal Weapons Charges Dismissed ... Case Smelled Fishy

Jeezy has scored legal vindication ... TMZ has learned weapons charges were dismissed this morning in court, and there's evidence this case was bogus from almost the beginning.

TMZ broke the story ... Jeezy and 5 others on his tour bus were arrested last August right before an Orange County concert. Cops found an AK-47 and a Glock on the bus and charged all 6 with felony possession of an illegal weapon.

Cops were on the hunt for a weapon that was used in a Northern California murder during a Wiz Khalifa concert a few days earlier ... a concert where Jeezy was the co-headliner.

Law enforcement sources tell TMZ ... the Orange County D.A. made the motion to dismiss the charges. The judge agreed. Presumably the motion was based on new evidence, but TMZ has learned, authorities were well aware early on ... this case didn't hold water.

Here's what authorities knew:

-- The 2 guns were owned by Jeezy's security chief, who was not on the bus. He was in the hospital because he was shot the night before during the Suge Knight shooting at 1OAK in Hollywood.

-- Cops had inspected the guns 2 days before and determined they were NOT involved in the shooting at the Wiz Khalifa concert.

-- The security chief purchased the AK-47 legally in Georgia, but it's illegal to possess an AK-47 in California ... yet the security guard was not charged. Jeezy and the other 5 people on the bus who were charged weren't in direct proximity to the weapon when cops boarded the bus. The gun was in a case behind the security chief's bunk bed, and Jeezy was in a closed, separate cabin. We're told DNA results confirm none of the 6 people arrested even touched the weapon.

And it gets worse. Authorities held all 6 people on $1 MILLION bail, even though the recommended bail for that offense is $20K. All 6 defendants sat in jail for 4 days until they got the bail reduced.

All 6 had their money, jewelry, clothing and other personal items seized, even though it had nothing to do with the alleged offense.

Short story ... the guns that were seized were legally purchased ... the property of Jeezy's security chief, and authorities knew it.

We contacted Jeezy and asked if he felt there was profiling and he said, "I pray this had nothing to do with race but it definitely had nothing to do with evidence."

Jeezy adds, "I knew that the allegations and charges were based on zero facts. I'm relieved that the truth has prevailed."
