It's my first thread here and I want to start with the issue that worries me a lot.
One in three people in the U.S. know someone who has been shot. On average, 32 Americans are murdered with guns every day and 140 are treated for a gun assault in an emergency room. Every day on average, 51 people kill themselves with a firearm, and 45 people are shot or killed in an accident with a gun. The reality is really frightening. Is there any hope, that the situation can change?
the most conservative estimates put the number of privately owned firearms at 200 million. using all of your numbers, that's 300 uses per day, assuming each use is a unique firearm, etc. which then puts the violent or otherwise undesirable usage rate at 3e2/2e6 = 1.5e-4 or 0.015%. so 99.985 of all firearms are used safely every day. not bad.
of course, those numbers could be better. so then it becomes: who are the people who are committing violent crimes with guns, how are they obtaining said guns, and why are they committing violent acts? who are the people committing suicide, why are they committing suicide, and how are they obtaining their guns?
there are many ways to tackle both issues. some of them are socio-economic (poverty, lack of economic opportunity), some are cultural (social stigma associated with mental health treatment), others are a law enforcement issue (war on drugs). others involve stripping people of their rights (forcibly taking firearms from people considered dangerous or have restraining orders, etc).
and before calling for the repeal of the 2nd amendment altogether, i would ask anyone whether you would consider giving up any other amendment, because you know once it's gone, it's not coming back. freedom of the press? freedom from unreasonable search and seizure? freedom from cruel and unusual punishment? and so on.
i lived in west philly for 5 years. i currently live in los angeles. i haven't feared violent crime at any point in my life when living in a city.
