In the aftermath of the battles at Lexington and Concord, the Massachusetts Provincial Congress held a series of hearings to determine who fired the first shot.
The purpose of the hearings was partially to find out exactly what had happened, but it had another purpose: if it turned out that the British had fired first, then the Assembly could turn to England and say “SEE? It wasn’t us!”
Even 250 years ago, Congressional hearings had a second agenda attached to them. (*sigh*) In the end, despite getting lots of testimony, the answer was still somewhat murky. But the Assembly still had enough information to give reconciliation one last shot.
