You insult my intelligence. I was able to spell the word 'imbecile' on only my sixth attempt. I can promise you that I did not use permanent sharpie on my hand.... maybe.

Once the US citizen supply depos are hit (i.e. The Mall and McDonalds) it will be over quick 

The NRA isn't too powerful, the politicians are too weak. If you go into politics just to have a career you're definitely the wrong person for the job. Corporations wouldn't have any leverage in politics if most politicians had a spine and actual convictions.

The NRA isn't a for-profit corporation though. It is a 501( c ) organization. Most of its power comes from the ratings it gives politicians which influence the voting decisions of gun owners. Republicans  are scared of being primaried when they represent populations that could be 60-70% gun owners. As far as its status as a PAC, it is very low on the list in terms of money spent on ads. The defense contractors, big oil, teachers unions, and other organizations have much more money spent on ads. 

Anyway it seems to me that if the politicians weren't scare of their voters voting them out, then what power would the people have over them to do what they say they'd do? They'd just all lie, do whatever they want, and get voted out the next term. Not as if they don't already lie anyway. 

Guns should be banned in American because the people can't be trusted to stay alive.

I mean they banned Kinder Surprise eggs because they are "dangerous"

Safety is number one priority.

Guns do not kill people, people kill people.

It is pretty hard to get an illegal gun here in germany. Not zero, but then this is ever the case. But I see that in Brazil you might have a different experience. But look at the result:

https://en.wikipedia.org/wiki/List_of_countries_by_intentional_homicide_rate

Germany has a homicide-rate of 0.85 (per 100.000 people and year), while Brazil has one of 26.74. It is 30 times a slikely to get murdered in brazil than it is in Germany. You're right about Japan, it is even three times lower than in Germany, they have a rate of 0.31. To make it clearer: In Japan you had 395 that year of count, on 130 million people. In Germany it were 682 murders on 80 million people. In Brazil that are more than 55.000 murders on 210 million people. Alone this dimension is crazy. So yes, restriction of gun ownership has effects. Sure, murder rate is dependent on a lot of factors more, but gun ownership is a contributing factor.

Ouch. This reminds me: even the number of gun accidents in the US is higher than murders in many european countries.
