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.
The current day government led a roguish and uncertain existence. These are people in power, having zero respect for the rule of lawz and these laws affects the common man. Social vices are the orders of the day in our present society, what must be done to prevent, rather reduce these vices? Job creation that will be available for the common because idle man is the Devils workshop. These people tends to be busy with work so they won't be less busy to think about committing crimes here and there. Self-defense is important in this part of the world. Remember, the world we lived in today is such a a cruel place, one will never get passed the ugly incidences happening. Crime is tough and leads to violence, loss and deaths. It doesn't give a country good name, rather a bad one. The government should provide jobs for the citizens, that's their duties as sitting influential men.
