回复：怎麽能出这种主意 ? 真的想害死人不成 ?

Reading up to this point, I think single old cat is a good person. Listen to his advise. Don't buy a gun. There was a report showed that normal people with guns are more prone to death in a violent situation that those without a gun. You are dealing with a professional criminal. You are not as fast and evil as the crinimal. Once the criminal finds you have a gun, you most likely will be the victim. Don't carry a gun. Be smart, know where you are. Don't be at a wrong place at a wrong time.

I severely doubt qwqw68's intention up reading to this point. I hope he is well. If you want to be successful in the society, you have to have a high moral standard, know what's wrong and right, do things that benifit to the society, to the people who associate with you. I hope qwqw68 will change to a person with a normal or higher moral standard.
