IMHO if the person wants to commit suicide they will. Having a gun is irrelevant for the fact that if they want to commit suicide they will do it no matter what tool it is. If its not a gun then it will be something else. Remember, a gun is only a tool. It still needs a persons brain to operate it. If someone wants to kill somone, kill themselves or anything else they will find another tool to do the job. A gun is just the most efficient tool for the task.
