You sounded reasonable in the beginning...now, you are beginning to sound like a propaganda bot that isn't able to directly engage in a reasonable conversation.
First off...if you aren't from the US, then how is it you have so much experience of the operation of our communities that you feel you are qualified to offer suggestions as to how to fix things? Your opinions are based on generic observations and principles and are not specifically applicable. Unless you have a greater depth of the functions of the US Republic system of government...you should probably refrain preaching your solutions to the problems.
Second...I don't trust the US government, not any other government that currently exists or any government that has ever existed. You are a fool if you trust your government. History shows that all governments will eventually become corrupt and fail.
Lastly...You are mostly correct that not much has been done to address gun violence...that is partially because people keep focusing on the gun and not the real source of the problem. But it is also because, gun violence is minor compared to what actually causes the deaths each year. Cars, Doctors, and falling each kill more people that guns each year...yet guns prevent more people from getting hurt than all of those combined.
This is my last post on this subject with you.
2)If you don't trust your government then why bother voting? Its fundamental for democracies for their citizens to engage in government which in a majority of cases is through voting. There is a required level of trust that a government needs from its citizens for the whole thing to work. If your opinion is in the minority then do something about it.
3)Your defence of guns comes down to the fact that guns are tools being used by criminals and that you should stop criminals as opposed to stopping how they commit crimes. That doesn't take into account how much damage guns do when used by criminals. Yes there are less deaths due to gun violence than the examples you gave, but that doesn't mean you should not do anything at all to address it. And your claim that guns prevent more crime is only applicable because of the expectation that your assailant could have a gun. Most of the industrialised world get by just fine without their use for self defence.
4)Since you aren't going to be replying anymore you're the one who's refusing to engage in discussion. Bye then and take care.
