Eh, you'd be surprised.  That's more or less what any law enforcement in the US will tell you. 

I mean even if you ignore the studies and statstics... it's pretty hard for people who actually have to deal with it to get past the numbers.

There are more guns in the US then people.  Even if you banned all guns it'd probably take decades to get to where you could make gun even slightly difficult to get your hands on.  If ever.  

Gun crime =/= crime.

Also... exatly what studies are you talking about... because generally the studies you read DON'T show that, and instead show that any drops in violenet crime were part of a trend of decreased violent crime that has been going on pretty much everywhere since the 80's.  

The only thing being lowered, is suicide as committed by guns.

I seem to recall you being Australian, so...

We've had this discussion before, but since the semi-auto buyback scheme introduced by the 1996 Port Arthur Massacre, there has not been a single gun massacre in Australia. Gun culture is not entrenched here like it is in the US, it is much, much harder to get hold of guns, especially the now banned semi-autos.

Hell, most drug dealers here don't even have a gun. They carry knives.

A) As has already been covered that's not really true.  There have been mass shootings, it's just that the actual death rates haven't been considered high enough to qualify.  

 Additionally, the population of Australia is like 7% the Population of the United States.   If you took all other things as even.

B) Read the studies.

C) Most drug dealers in the US don't carry guns.    A lot of them are felons.. and its a crime for a felon to carry a gun.   Shit in the state I live in if your a felon and you have a gun you get 10 years in jail.

Generally criminals keep their weapons at home unless they are planning to comit a crime/think someone is after them.

Also, i think you understimate the gun blackmarket.

Guns bans successful in lowering both gun homicide and gun suicide rates in Australia:

http://andrewleigh.org/pdf/GunBuyback_media.pdf

"their findings discount a previous study in the British Journal of Criminology in 2006, which found the buyback had no impact on either gun homicide or suicide rates."

"models used in that study [the ones that found no reduction] were not appropriate and results were  inconsistent."

Nope your delusional if you think banning guns is a good Idea. Please  note to everybody I never once said anything about gun control being bad. The only thing I said was a bad Idea was the ban or any form of ban on guns if you think banning guns is a good idea then like I said your delusional. Resaonable gun control is fine. 

Have you read the actual study or are you just supporting it because it fits in view with what you want to believe?

I noted you quoted the press release instead of the study in a journal or something.

Why it's often discounted?

They use gun buyback rate per capita in each state... without controlling for number of guns in each state.  

As opposed to gun buyback rate as a percentage of gun ownership.

I think it's self explinaitory why that's a problem?

Additionally, another flaw in their data as they note. More Urban areas are expected to have higher buyback rates.

Urban areas also happen to be where violent crime rates have been dropping most... more or less world wide.

The first studies control for this.  This study... does not.

Reduced gun homicides and suicides followed the introduction of semi-auto control, while non-firearm homicide remained stable for the same period.

But this is going nowhere. We'll each google studies that support our side, and argue round in  circles, and neither of us will change our opinion.

I'm glad I live in a country where guns are controlled, and I assume you're happy to live in one where they're not.

Actually no.  That's not true.  You either didn't read the study and look at the statistics or didn't understand them.

Non-homicide rate also dropped over the same period... and all three led the gun control measures.

Additionally, Non-gun sucicide INCREASED after the gun ownership ban, as the study noted, the increase was over 100% the amount of the loss in gun suicide rates after a few years.

Since you got this wrong, i feel like I might need to explain why the study was flawed more in depth.

The study you cited stated the buyback effected crime because the raw number of guns bought back saw the highest reductions of violent crime.  Even though those areas weren't the biggest percentages of guns bought back.  

Also, they actually walk back the claims on homicide

"It should be noted that the standard errors on these estimates are fairly large, so that estimates of the declines in firearm homicide rates are usually not statistically significantly distinguishable from no effect"

Which usually in the science community would mean "There is no effect".  

If you want to press a point though......

If you actually read the study you googled... I think this very much could go somewhere, as you can note the faults first hand.

Meanwhile assault has gone up every year that the assault weapons ban and more strict gun policies has been in effect (1997)
