This always bothered me .
How did MAcalister become the leader if the BA.
How can a small time sheriff magically own thousands of lives with politicians and judges as well.
One must aquire power somehow , you cannot just start mafia from scratch! The illuminati (if real) wouldnt of been started by a firefighter. Jokes

The BA must have higher up with a lot more money and power still out there.
Where does the BA 's power trully come from? Visualize maybe?
Haffner's threat coming through?
Both he and styles faked their deaths and used Maclister as their pawn.

Side note of the new show:
Its pretty blatant that Fischer is the same is Van pelt. Both get called out by jane for having tramatic past experiences. Fischer saw a shrink GVP bottles it up and told no one not even herself.
Wylie is Rigsby. Awkward at first friends with cho and it magically smart at times with all the answers.
