Regrets ... He Had a Few

Shia LaBeouf Leaving Court
Shia LaBeouf looked like crap as he left the courthouse Friday ... after being arrested for essentially going insane inside Studio 54 in NYC.

Shia had remorse and hangover written all over his face as he walked away, just having pled not guilty to criminal trespass and disorderly conduct.

Shia allegedly threatened cops, yelled obscenities at patrons inside the club and disrupted the performance.  He also gabbed an ass or 2 during his drunken tirade.

Witnesses say the actor was acting bizarre the entire evening and looked dirty and unkempt.
