Alec Baldwin Says Security Vid Proves No Punches in Parking Spot Fight

Alec Baldwin's foe in a bitter battle over a parking spot lied when he said Alec punched him ... and the actor says he has video to prove it.

In new legal docs obtained by TMZ ... Baldwin's attorneys, Luke Nikas and Alex Spiro, say there's video surveillance footage proving he didn't punch or attempt to punch Wojciech Cieszkowski during their parking squabble in November ... squarely contradicting the man's story.

Instead, Baldwin claims the footage shows both men standing face-to-face during their argument before Alec "lightly taps" the other guy's chest. Baldwin is adamant ... claiming he never threw a punch, and now says the video irrefutably backs him up.

In the docs, Baldwin also claims Cieszkowski's own medical records prove he didn't suffer any injuries ... and get this, Baldwin claims the guy's doctor recommended he take a SINGLE Tylenol and that's it.

As we reported ... Baldwin was arrested for assault after the incident, but cut a deal in January to plead guilty to a lesser charge of harassment in the 2nd degree and accept anger management classes as punishment.

But, that wasn't the end of it. Cieszkowski sued Baldwin last month for assault and slander, maintaining the actor punched, shoved and ruined his reputation by going on 'The Ellen Show' and saying he thought Cieszkowski was going to run over his wife with the car.

As for the slander allegations ... Baldwin's calling BS and says his comments to Ellen were just opinion.
