That's the point I hopefully made in my other reply.  I think society has been desensitized to violence and that is the root issue that needs to be addressed.  Not so much "let's ban another gun component or write another law that will be ignored by criminals".

kids buy weed and it's illegal. Making guns illegal won't solve the problem...The US issue around mass-shooting is cultural issue that won't be solved via legislation. If these sickos can't find a way to buy guns, they will build bombs with stuff you can buy off the shelf.

Respectfully, I disagree.  Owning a gun does not infringe on your right to safety.  Using a gun in an illegal manner to inflict harm infringes on your right to safety.  Guns have been around for hundreds of years, yet now all of a sudden it's a problem and something needs to change?  I think there are much deeper societal problems at the root of violence.
I believe we need to address the issue of violence in general versus worrying about changing gun laws just to make people *feel* better, like the government is addressing the issue.

Just so you know...  In the US you DON'T have a right to safety.  You DO have a right to a gun.  The idea being that, as an individual, with a gun, you are best able to make decisions that maximize your safety.

Yes, politicians have the responsibility to enact laws that effect everyone, this is true.  Laws "should" effect the greater good, I also agree.  Yet congress is exempt from the laws they make, so would they really care how it effects their constituents?  I try not to generalize, but the last few decades it has seemed like members of Congress care less about the people and more about their own well being.  They play lipservice to the issues and do nothing.  But I don't want to get off track here because that is a completely different issue.
Society in general, I feel, has eroded in the last 20 years.  When I was growing up, I learned (and felt) the consequences of my actions.  As a result, I slid down a hill on ice and hit a parked car.  I went door to door until I tracked down the owner so I could take care of the problem and exchange insurance info.  Conversely, kids in the parking lot of my work were playing around my car.  I walk out later and find a huge dent in the panel.  They ran into my car (or leaned on it or whatever) and they caused damage.  They ran away.  Now I get to pay for it.  There is a general lack of respect in much of the latest generations.  Many kids are not brought up to understand there are consequences to there actions.  This is a problem with society where people either don't understand or don't care about how they effect other people.  I'm talking about individuals minding their own business.  I'm talking about individuals respecting each other.And I'm talking about individual's freedom.  Freedom to do whatever they want as long as it does not harm anyone else's life or property.  
I understand guns are an emotional issue, but they aren't the source of the problem.  Murder with any other item is still murder.  So let's address the societal source of violence and lack of respect for life.
