What law was the protester breaking before he was shot? From the video I've seen, there was no justification. Am I missing some context from your statement?
I guess it depends on what was meant by "I state again that the constitutional right to bare arms is a f?ckin sad joke because they are not being used against a tyrannical government, the very reason it was put into the constiution."
I interpreted this as referrinmg to an armed insurrection.
As a practical matter, it is almost never legal to use force

I'm not aware of any court cases involving a successful "tyrannical government" defense.
Regardless of reason the Second Amendment was added to the Constitution, it does not alter the law regarding self defense or resisting arrest.
