First off, there's the intro riff which is also the chorus part:
repeat 4x
E- | ----------------------------------------------------- |  | 
B- | ----------------------------------------------------- |  | 
G- | -2-2--2-4-2-----2---5-4-----5---7-5-----7---5--4h5-7- |  | 
D- | -2-2--3-3-3-----3---3-3-----3---5-5-----5---5------5- |  | 
A- | -0-0--------0-0---0-----0-0---0-----0-0---0---------- |  | 
E- | ----------------------------------------------------- |  | 


After you go through that twice, however, there is this little bit of lead
that kinda copies the vocal line of the chorus:
E- | ---------------------------------- | ---------------------------------------- | 
B- | -9b10r(b9)-------------------------- | -10--10----10-12--12-10-12-13--13-12-13- | 
G- | --------(b9)10---10-b12r10--9h10---- | --------12------------------------------ | 
D- | -------------------------------12- | ---------------------------------------- | 
A- | ---------------------------------- | ---------------------------------------- | 
E- | ---------------------------------- | ---------------------------------------- | 


E- | ------------------------ | 
B- | -12b15r12-12h13-10~~~~~~ | 
G- | ------------------------ | 
D- | ------------------------ | 
A- | ------------------------ | (rhythm guitar ends on  A5 )
E- | ------------------------ | 

The A5 is sustained throughout the verses with a few changes like so:

A5
Last night the word came down
( A5 )                 G5 C5 A5
Ten dead in Chinatown
( A5 )
Innocent, their only crime
        B5                   slide to C5      A5
Was bein' in the wrong place at the wrong time
( A5 )
"Too bad", people say,
( A5 )                            G5 C5 A5
"What's wrong with the kids today?"
( A5 )
I'll tell you right now they got nothin' to lose
G5               F5      A5
They're building EMPIRE.


Then this little lead bit:  B- | --8b10-(10)-(10)-- |  (sustained indefinitely)

While the rhythm (once again) stays on  A5.  Do the whole verse bit
over again for the second verse.

Here's the pre-chorus with some lyrics below to help you keep up (repeat
the first section twice, then do the last bit right before the chorus):
E- | -------------------------------------------------------------- |  | ------- | 
B- | -6---6-6-3--3-3--8--8-8-6--6-6--6--6-6-3--3-3----------------- |  | ------- | 
G- | -5---5-5-2--2-2--7--7-7-5--5-5--5--5-5-2--2-2---5--5-5-5--5-5- |  | ------- | 
D- | -0---0-0-0--0-0--0--0-0-0--0-0--0--0-0-0--0-0---5--5-5-5--5-5- |  | -3/5-5- | 
A- | ------------------------------------------------3--3-3-3--3-3- |  | -3/5-5- | 
E- | -------------------------------------------------------------- |  | -1/3-3- | 
   East side_________      Meets   West side___    downtown_____.
   No   time_________        the   walls_fall____  down_____.


After the second chorus, play this right before the bridge (the
"bridge" is what I call the part where that guy does the commentary on
law enforcement):
E- | ----------------------- |  | 
B- | ----------------------- |  | 
G- | -5-----5-----5-/7~~~~~- |  | 
D- | -5--5--5--5--5-/7~~~~~- |  | 
A- | -3--5--3--5--3-/5~~~~~- |  | 
E- | ----3-----3------------ |  | 

Then play this part clean (actually with chorus and slight delay...
but what the hell) during the commentary:
E- | -0---------------------------3------------------- |  | 
B- | -3----3--3h5--3----5-6-5-3---3---5----5-6--5h6p5- |  | 
G- | -2----3-------2----5-5-5-2---0---5----5-5--5----- |  | 
D- | -0----------------------------------------------- |  | (repeat 4x)
A- | ------------------------------------------------- |  | 
E- | ------------------------------------------------- |  | 

(When the commentary gets to "By way of comparison..." a second guitar
should start chunging out an open D string with distortion and palm
muting.)
