Re: How long did Nolans Batman actually fight crime?(SPOILERS)
As long as you want to think that he did .
BB and TDK dont specifically say the first six months and the next six months .
I imagine a 2 year gap between the first two films.
So, 4 years active .
And,even though he was retired for 8 years,
Batman was still wanted by the police .
That means he was part of the consciousness of Gotham City For 12 years .
Just look at it in real time .
There is nothing in the story that says that you cant.
