Mr Reed was accused of destroying a different Ten Commandments monument in Oklahoma three years ago, media reports say.
He was diagnosed with a schizo-affective disorder (a mental health condition) after that incident but was released from hospital in January 2015 as part of an agreement with the Oklahoma County district attorney's office in which he pledged to continue receiving treatment and therapy, Tulsa World reported at the time.
The initiative to build the statue was led by Arkansas Senator Jason Rapert, who sponsored a 2015 law to display it on state grounds.
Mr Rapert said it "honoured the historical moral foundation of the law".
But opponents including the American Civil Liberties Union said that its appearance amounted to "an unconstitutional endorsement of religion" - they threatened to take legal action to have it taken down.
The statue was financed by more than $26,000 in private donations, local media reported.
It's an example of Lucinda Wierenga's sandcastle skills. Next time you come to South Padre Island, think about taking a sandcastle building class from Lucinda. As expected, Spring Break youngsters (most likely) have destroyed several of the sandcastles on the island. But there's more sand.
I cannot imagine a God who rewards and punishes the objects of his creation, whose purposes are modeled after our own - a God, in short, who is but a reflection of human frailty. Neither can I believe that the individual survives the death of his body, although feeble souls harbor such thoughts through fear or ridiculous egotism. It is enough for me to contemplate the mystery of conscious life perpetuating itself through all eternity, to reflect upon the marvelous structure of the universe which we can dimly perceive, and to try humbly to comprehend even an infinitesimal part of the intelligence manifested in nature.
We atheists lead happy lives, never concerned with the-dying-and-burn forever-in-hell nonsense. We know better. We enjoy happiness with our friends and neighbors and ignore all the greed and rituals that pay the parasite priests. Let them wallow in their medieval superstition while we enjoy all the wonders of our God-free universe.
As a scientist, I can not help feeling that all religions are on a tottering foundation. None is perfect or inspired. The idea that a good God would send people to a burning hell is utterly damnable to me. I don't want to have anything to do with such a God. I am in infidel today.
