What about the guns bans?

Many times, we hear politicians talk about common-sense gun control. Here is a list that many will hear and the list are assault weapons, gun sales and other half measures.
These ideas are rooted from the 1960's.
The people that promote the 1960's idea like to think that fewer guns means less gun crime.
If we look further in this idea, the people that pushed this idea should push for a bigger ban what they currently promote.
The late Sen. Howard Metzenbaum said, "If you don't ban all guns, you might as well ban none of them."
Again, few people in power want a partial ban on guns don't want a full ban because a full ban on guns have no popular support. Here are some facts, California tried a vote on banning guns in 1982 and the people were against the idea and Massachusetts tried this in 1976 and the people hated this idea.
Some people are looking outside the country for help. Australia in 1996 had an interesting idea.
A man killed 34 people in Tazmania by a semi-auto gun and the government banned semi-auto guns and repeating shot guns and the government took 700,000 registered firearms. The total was 3 million in total.
The ratio of guns in the United States with type of ban would take away 150 millions guns away but at the same time, there would be 200,000,000 guns that people would have and this does not include hand-guns.
If you don't know, hand-guns are 80% of gun crimes.
You want to know in the 2007 International Small Arms survey in 72 countries, only 1/3 would comply. If the people of the United States are similar then there would tens of million of small arms in the black market.
The sad news is that politicians will play both side the fence. They purse the votes of gun owners and they want to ban bad guns.
Again, the issue is that their policy don't affect the issue, then blame the gun lobby.
If you want to ban the semi-auto guns then attack and describe the supply-side policies and how people that obey the law can keep their weapons.
If they can't solve the these issues then let it be. Criminals will always get there weapons but should we disarm people while bad people have theirs.
