Conrad Murray came back to Trinidad, celebrating Carnival -- and he gave his son an official introduction into the world of BOOBIES!

Murray returned to the place where he became the man he is .... glowing in the sunlight of freedom ... and also glowing from the reflection on his head.

The man who did hard time for Michael Jackson's death brought his family along for the topless extravaganza .... and his son is clearly fully indoctrinated.

That V isn't just for victory.
