What is the "shot heard round the world" if it hasn't happened yet? A kid dying on camera like Tiffany Dover?
The "shot" would be a unifying event that sets the whole thing off and begins shifting the tide, just as it did back in 1775.
Considering the tide hasn't shifted, I don't think the jab is "the shot", but it most likely will be a big part of it.
Not yet.
The "shot heard around the world" will be known by all. There won't be any guesswork as to whether it is or isn't.
