John: Take a look. https://en.wikipedia.org/wiki/List_of_school_massacres_by_death_toll . It's a list of Campus Killing. However, it's just a tip of the iceberg. Why? Let me tell you. The definition of Campus Killing is that someone's students kill nobody. In order to protect someone's students,  Miuson kill people.

Me: Ok.

John : How does it work?  Mr. Duan is Kelvin's students students. Kelvin is Miuson's students. Have a look.  https://en.wikipedia.org/wiki/BBK_Electronics . It's a spy's company open by Kelvin.  

.

Me: This spy's company is listed in Bahrain's bourse.

.

John: Yes,. Mr. Duan is in charge of this spy's company.  Mr. Duan is Kelvin's students.

Me: Ok.

.

John : In fact, Kelvin teach Mr. Duan a lots of hacking techniques.  One of the techniques is "How to hack a bourse".

.

___

.

Bradley : Stop touching the bourse. Tell your students either to kill people or get killed by me. 

.

Miuson : Which students?

.

Bradley : Kelvin and Mr. Duan.

.

Miuson : Piss off.

.

.

John: After the argument,  they both leave. Guess what happen.  Take a look.  https://en.wikipedia.org/wiki/Tsui_Po-ko . Miuson ask a killer to kill 4 persons . The victims are 3 police and 1 security man respectively.

.

Me: Is the perpetrator called Tsui Po Ko? Is the perpetrator a police?

.

John (Shaking head) : No,. The perpetrator isn't called Tsui Po Ko. The perpetrator isn't a police. Indeed,  we don't know the name of the perpetrator . We just assume.  The killer is called Mr. S.

.

Me: Ok.

.

___

.

John : Why did you ask Mr. S to kill people?

Miuson : Bradley said, "Stop touching the bourse.  Ask your students either to kill people or get killed. ".  Therefore,  I ask Mr. S to kill people. 

John :  Your students mean Kelvin and Mr. Duan,  not Mr. S. 

Miuson : Oh! I misunderstood. 

John : You didn't misunderstand.  You pretend to misunderstand.  You mean to let your students,  e.g., Kelvin and Mr. Duan be exempted from killing people. 

.

Miuson : No,. I didn't mean that. 

John : Yes,. You mean that. 

___

.

Me: Then, did Kelvin and Mr. Duan know that Miuson on behalf of them kill people ?

.

John: I'm not sure. However, I can give you a ratio of responsibility. 

.

1) If Kelvin and Mr. Duan know that Mr. S on behalf of them kill people,  Kelvin and Mr. Duan is protected by Miuson 40%. 

.

2) If Kelvin and Mr. Duan know that someone on behalf of them kill people, however, they don't know who that person is,  Kelvin and Mr. Duan is protected by Miuson 70 %. 

.

3) If Kelvin and Mr. Duan don't know that someone on behalf of them kill people,  Kelvin and Mr. Duan is protected by Kelvin 100%. 

.

Me: So, how many % are Kelvin and Mr. Duan being protected by Miuson?

.

John: About 85%.
