Ok, if we're going to do gun ownership, here's some of the main points as I see them.
For gun ownership
- Used for hunting, sport, or leisure
- If criminals think your armed, they are less likely to commit crimes for fear of being shot. (crime deterrence)
- It levels the playing field to some extent as the old and infirm have more chance to defend themselves. (crime defence)
- Range/target shooting as a sport or leisure activity.
- keeping the government in check.
- Criminals have guns anyway, limiting law abiding citizens ownership only makes it easier for criminals. (laws only affect the lawful)
- A gun is a tool, if you ban guns criminals will simply use a knife.
Against gun ownership
- The main source of illegal guns is legal gun owners. If the general public don't have them then the criminals will loose their main supplier.
- Safety risks ie. kids finding guns and shooting themselves, people mistaking family members for intruders and shooting them.
- Escalation of violence. Gun crime is higher in countries with legal civilian gun ownership. (the criminals need guns to protect themselves and have far easier access to guns)
- A criminal with a gun is significantly more likely to be successful than an unarmed one. (by forcing criminals to be armed, they actually get more likely to succeed at committing crime, not less likely)
- Guns are crap at stopping tanks and bombers hence would be useless at stopping the army. If the army sides with the government or the people or splits between them, ultimately it's the army that will determine who wins. Random civilians with small arms will just get themselves killed.
- The abnormally high homicide, rape and violent crime rates in the US indicate that gun ownership doesn't deter or stop criminals, it appears to make it easier for them.
- There are plenty of other hobbies that don't involve guns, just do one of them instead.
Personally I think the general public don't need firearms, but I also believe that the USA has managed to find the absolute worst of all worlds. The guns are available, so the criminals have both the motivation and easy opportunity to get a gun, but the law abiding citizens do not have the freedom to make the most out of their gun ownership to counter the problems that are created when large numbers of criminals are armed (gun-free zones, it's not legal to carry a concealed weapon in some areas etc.). Both sides have a case and if either side won on the issue it would be better than the current crappy middle ground that currently exists.
