Unfortunately I've only got a few minutes so I can only argue one point:
>>Ok PJ simply because I don't want to debate the merits of a survey with you, I have work to do, lets assume the lowest value for the number of defensive gun uses in the source you provide. Lets assume that it is only 108,000. Even at that low amount that means that guns are used for defense almost 5 times more often then they are used to commit murder. 108,000 / 22,000 = 4.90909...<<
Now you are comparing ANY defensive gun use with only gun murders. The 108,000 includes such glorious things as some guy was looking at me funny in an alley so I pulled out my gun, and I saw a burglar and pulled out my gun when in reality it was just some poor homeless man who crashed out drunk on the guys lawn. Now, to the 22,000 murders, add on accidental deaths, gun crimes that could not have been committed without the gun, AND of course the thousands of injuries that aren't included in the murders because the person wasn't killed just very badly injured. Now you'll see that the numbers are greatly against defensive gun use.
We've already shown that the idea people will kill without guns anyways is flawed. The only proof that they are used defensively on a regular basis is a flawed 10 year old survey. And every day more and more people are getting killed and injured by guns that are easily available and that are so simple to use a 5-year old can kill a grown man! If you know some magical way to know who will and who won't use a gun properly then let us know, but I know that humans are idiots are for every 10 law abiding citizens there's some moron who might use his gun (or leave it out for someone else to use) to the detriment of someone elses life if the circumstances came about. And the fact that you are willing to sacrifice these peoples lives under the unlikely assumption - brought up by the flawed survey - that it might help you someday just staggers my mind!
And unless your friend had plans on petting the crocodile, the thing is NOT dangerous. Jeez, call the cops, they get there in a few minutes with animal control, and just stay upstairs. But no, with a gun its always shoot first ask questions later
