No arrests! Why?

Now we are 99% sure Suge Knight wanted both rappers dead and this is the person who started the murders. He got his 'business partners' to plan and release the killings as Knight had a lot of money back in the day and a strong group of people behind his back who supported him, as Suge had a lot of power. Knight took a few notes out his purse and the mission was passed!

All this conclusion was fair easy to find out and if college kids like me were able to come up with it, then why the police struggles so badly with the cases and never arrested anybody for being behind the shootings of Tupac and Biggie? Let's listen to the inspector again:

Exactly. The police could easily solve these cases and release the truth to the public but they did not and seems like they will never do because as we now know, the Notorious B.I.G. has been killed by past FBI workers and the police is so ashamed to say that because they would loose their authority in the eyes of the society! This is exactly what happened!
