Wednesday’s execution of convicted murderer Troy Davis sparked heated, passionate debate, though perhaps no protests reached the same level of vitriol as a Twitter exchange between actor Alec Baldwin and conservative commentator Michelle Malkin.

Baldwin live-tweeted a chronicle of events as they unfolded Wednesday, including the Supreme Court’s refusal to grant a last-minute stay of execution. Once it was announced that Davis was dead, shortly after 11 p.m., Baldwin turned his ire toward Malkin, who had also been following the developments:

It didn’t stop there. Over the next couple hours, Baldwin attacked former Vice President Dick Cheney, former Defense Secretary Donald Rumsfeld and the “blood-thirsty right wing trash”:

On her own Twitter page, Malkin began re-posting and responding to some of the hateful, racist slurs she began receiving from other online users, presumably at Baldwin’s behest:

It appears Malkin was the first one to engage Baldwin Wednesday night with the following tweet touching off the ensuing back-and-forth:

Regardless, the sheer level of maliciousness Malkin received in return is decidedly stunning.

Incidentally, Baldwin’s attacks on Malkin did not end Wednesday night. Thursday morning, he posted:
