No, I don't! For me Its not necessary to have a gun, the more important is you are always alert and careful in your society. If you are in danger you can shout to get attention of others to find some help and always use your skills when way you are choosing, I think you can feel if this way is safe or that way is safe.
It depends on the community you're in. There are some places in the world, where you can scream all you want and nobody will help you. It's important to rely on yourself not on others. What would happen if every person always wanted others to save them, think about it. We'd have a society of losers who lean on each other and when one person fails to do their job they all fall like dominos. I don't have a gun but I'd like to have it and I'll try to buy it in the near future.
