Stage III - Guns or Violence? What are we really trying to achieve here?

After the Newtown incident, all that has plagued the news is guns.
“Guns should be banned”
”Guns should be allowed”
”Guns bla bla bla”
However, after having taken some time to think about it, I agree with Peggy Rambach’s opinion on how Stricter gun laws alone won't stop America's urban violence.
Her goal I can only presume is to reach the whole American populace as audience in an attempt to spark some more thought into what the real cause of violence is. Is it the fact that laws on guns are so lenient?
In her article, she talks about her class of incarcerated criminals at Suffolk County House of Correction being moved by a poem that seems to accurately describe how guns and ultimately the power they provide to the wielder ends up corrupting him to the point of fatality.
However, she makes the point that having stricter laws on guns won't do America much good because criminals, keeping true to their title, are not particularly well known for following the law. If they require guns, they will get them through whatever means necessary either for protection or for mischief.
I agree with her logic and believe that this issue is much like the weeds that we find in our lawns every year. In order to really remove them, you have to attack them at their source.
Think about it: Imagine if for some strange reason, everyone in America agreed tomorrow that all guns should be banned and taken away from every single person within the borders of the United States. Would this automatically make gangs like MS13 a thing of the past? Would the bloods and crips stop fighting?
I think not. If history is any indication, they will just try to stay one step ahead of the law and create a bigger black market for guns, or improvise on how to do harm.
This has been observed in countries that have banned firearms such as the UK, where the threat of a pipe bomb is usually far scarier than that of a stray gun bullet.
I believe that the government should institute an investigation panel that will outline the root of why violence is spread throughout society and from there, devise laws and programs to correct or eliminate these factors altogether.
