Does America need the law of the jungle - the second amenemnt to the US Constitution?

A mentally deranged man can buy guns; and he shoots to kill 26 people, including 20 lovely little children, at an elementary school. And the President of the USA weeps. His administration and the US Congress remain essentially impotent spectators of this kind of horrible tragedies! One man can buy more than 30 high-powered guns; and he shoots to kill 58 people and injure more than 500 people in an outdoor concert. And the President of the USA is proud to be an American because of the professionalism of the hospital staff that treated the injured and of the victims that showed the bravery to help other fellow victims. But his administration and the US Congress remain essentially impotent spectators of this kind of horrible tragedies! The tragedies keep repeating!! Isn't it overdue for the USA to repeal the second amendment to its Constitution? In civilized human societies, shouldn't ordinary citizens get protection through laws and law enforces? Should they need private ownership of guns? Should guns be so easily available in this country?
I don't think you understand the US system, the current US "president" and the republican led US Congress aren't impotent spectators in this epidemic of violence that over 300 million firearms in civilian hands creates in the US, they are accomplices in this ongoing massacre that is only made possible by hundreds of millions of guns on the streets. They take huge "donations" from the NRA and the gun industry and then make damn sure that no laws are passed that will impede the introduction of millions of more guns a year onto the streets. This about pure naked capitalism hiding behind the 2nd. Amendment, nothing more. The entire US political system has been corrupted to the point where it only protects those who are the most ruthless and greedy. The people selling firearms and those who they pay to protect them from any negative repercussions. So yes the law of the law of the jungle is at work in the US, but not just on the streets. It is also the driving force in the halls of power and business in the US to the highest level. There is no chance at all that the 2nd. Amendment will be challenged at all as long as there are republicans in power in the US. You are right, "impotent spectators" is not the appropriate description of the corrupt gang that runs this country. I stand corrected. (I suppose I was thinking of Barack Obama's weeping after Sandy Hook when I used that mild and inappropriate phrase). I am pleased that you also feel that the Second Amendment is a law of the jungle. It is indeed too sad that there is no chance for that amendment to be scrapped any time soon. As I noted earlier, even the Democrats do not talk about scrapping the Second Amendment. I think it is very important for organizations like the Center for Inquiry to talk about this shame of the USA.
