RE: I'd like to own a gun

I read about the procedure to get a gun license and it felt like camel through a needle type stuff.
It doesn't seem that bad compared to getting a driver's license or whatever

What you should do is see if you can find a firearms lawyer to file your application for you, or grease a few palms, depending on how corrupt your local officials are.

Looks like you are limited to shotguns but shotguns are great for hunting just about anything and excellent for home defense.

If the process is intimidating just take it one step at a time. Tasers are ok but you only get one or two shots with them and they are expensive. Do you have a machete?
