Not so funny. And the not so funny part isn't the part about how cops are going to start to be taken out, (as the saying goes) by an angry public. The not so funny part is that the Federal Government just might step in to protect the cops, by declaring martial law.
What would happen if martial law were declared over cops being executed? Who knows for sure? But it might include a complete fall of the United States of America. Why? Because the people and their guns out-man and out-match the military, especially with most of our military being overseas, and especially with a whole lot of the military that would join the ranks of the fighting civilians in one of a multitude of ways.
