This is where the problem begins and ends. Gangs rule by fear, its an instinct humans have to protect themselves from danger.
You want to fight the problem, you fight fire with fire. These people don't care about laws, jail does nothing to stop them, it just delays the inevitable. They are worthless individuals who are a burden on society from every angle.
You want to stop these people you start killing them. You think when their homeboy drops dead on the street with his throat slit it doesn't get their attention? I don't envision a world where people are cut down in a storm of gunfire for doing wrong, but our laws don't work for everyone. We have legally tied our own hands when it comes to dealing with them and they know it. They exploit our own justice systems to work in their favor.
There is no rehabilitating these people or helping them, nor do we owe it to them. They are monsters, they have chosen a path in life.
Please tell me that if I had a gun to a mans head who raped your daughter, mother, sister or someone else close to you, that you would tell me to put it down.
Laws are our boundaries, but reality is its master.
