Its not just in the US, here in Europe its same, you start killing and acting like a rabid dog , you are done.

Here we had one big group that controlled everything for past 10 years, that group had state behind them , going around with presidents son , meeting with top politicians and so on. One part of that group was super violent , people were going missing every month , there are photos of them cutting their heads, arms, torturing them and so on. Everyone were afraid of them ,you see them in the clubs/restaurants you don't dare to look at them. You know where they are now? Doing 40 years to life. Other part of the group ? Still free and doing business.
