It seems like it's time to start learning self-defense yourself. What else? The authorities won't always help, and it won't take long to harm a person, so you need to figure it out on the spot. Carry a taser and a can of pepper spray.
Yes, it's good to learn sef defense like learning how to fight karate and having a pistol everywhere you go so that you don't get robbed easily. The only way the government can reduce crime rate is to provide adequate jobs for the people so that no one would come to complain that they don't have a job. We need to make sure we protect ourselves so we don't have to face unnecessary drama where the police are not available for us. There are so many things that are happening in the world and we need to get prepared for the worse.
