I think that in places like Texas where the trespassing is a common stuff, the people need a way to protect them self. But if you own a firearm you should keep it in a place where nobody can find it or reach it. In order not to happen many unwanted things
Similar to keeping cleaning materials far away from little kids. (sometimes they have a security lock).
Strangely enough there are a lot of gun incidents in the US, but much less so in other countries where owning guns is normal. (Swiss and others)
I think that any adult who is mentally healthy should have the right to have a gun. When laws do not permit to people have guns we end up only criminals have them and that is not fair.
How would you judge who is mentally healthy and who is not? Who will pay for these tests?
Who? That's the part of government, they should implement and issue a regulation, like drivers license if someone's getting a car. Just like a person buying a car, he needs to have license first before he drives on the road. That's what government do too when someone's buying a gun he needs to have a gun license that's being issued by the government to know if he's authentic to have the rights having a gun.
