A subsequent decision of the Supreme Court can overturn a previous decision. And it is not necessary to amend the Constitution.
Technically yes, reality no.....
Aside from the fact that the USC rarely, if ever, overturn a previous opinion.....as previously stated, both conservative and liberal judges agreed on this issue.....
IMHO, the flag issue is a small issue compared to all the other problems that need immediate resolution....
Don’t get me wrong, I wouldn’t mind if the USC reversed its decision but there are bigger problems that require all of our attention then a bunch of pissant, crybaby liberals burning the flag......
