TMZ Sports has obtained the video of the Starbucks dispute that led to Terrell Suggs' arrest last year ... and in the footage, you can see the ex-NFL superstar did indeed brandish a gun during the tiff.
The altercation took place at the Scottsdale, Ariz. coffee shop's drive-through on March 10, 2024 ... after a man alleged Suggs ran into his car while trying to back up to better reach the establishment's intercom.
The video shows the guy told Suggs he hit his vehicle -- but the former Baltimore Ravens pass rusher didn't seem to care .
