Jermain Taylor -- Bizarre Bathtub Video ... After Shooting Arrest

Boxing superstar Jermain Taylor -- the WBC middleweight champ -- released a disturbing new video in which he essentially apologizes for firing a gun during a MLK parade in Arkansas.

The footage is shot while Taylor is taking a bath -- and he addresses the incident in which he was charged with 5 counts of assault for allegedly squeezing out two shots during an altercation with a man and his son.

"I know y'all disappointed in me ... I'm sorry if I let anybody down or hurt anybody."

But here's where things get even more puzzling -- the 36-year-old says he had a beef with parade organizers that day because none of the kids at the event had any candy.

"Y'all need to get it together," Taylor said to event organizers ... "Had my little girl out there. Nobody had no candy."

Taylor then suggests he could be in jail for next year's parade -- and says he won't try to duck serving time by claiming he has drug issues.

"If I gotta go to jail, I'm gonna sit my ass in there ... but I'm not gonna say I have no problems with no drugs to get out of jail ... I worked too hard for my life to put that in it. So you can kiss my ass."
