As someone who does spend time around people with guns - Nope I do not fear people protecting themselves. You do not shoot unless you know your target, what is around it, what is behind it. Standard hunting rules apply.
and FYI went to a church for close to 20 years that allowed firearms on the property and in the church - guess what no one was ever harmed by a gun on the property. Many kept guns in cars to go hunting before and after church, several had CC and did carry. Several cops were often at church in uniform to go to work after church and all were armed.
Now I understand that you fear everything as it relates to guns and that you need to go out into the real world in a bullet proof hamster ball.
