Remove ambiguous warning

Remove the warning that said "This is different to the total number of
convictions, since we are picking specific groupings."  I really
have no idea what was meant by that.
Moderate statement about availability of overall case counts

We have seen some data about overall cases filed,
https://performance.cookcountyil.gov/Public-Safety/Number-Of-Felony-Cases-Filed-By-Felony-Class/kcfs-dufbm,
at least felonies.

It's still true that this isn't enough to verify the completeness
of our data set.  Try to change the language to acknowledge that
there is some aggregate data, but not enough.
Recast mapping question

"All maps" seems too broad a generalization, especially when we
aren't linking to any of these maps.  As a general trend however,
it's common knowledge that there are concentrations of
"negative social effects" on the South and West Sides.

Also capitalize "South" and "West" per AP style.
Fix text decribing convictions rate map

Re-cast language that seemed to suggest that any Chicago neighborhood
has higher conviction rates than the suburbs.  This isn't true.

Use "fewer economic resources" instead of "economically depressed".

Remove repeated instructions about how to use the map.
Add background on mapping decisions
Add context text to top charges map
Add methodology details for crime categories
Fix text for youth crimes

"What the data does indicate is that Cook County has convicted more
young people between the ages of 18-24 than all other age groups
combined."

That's not true.  Fix the text so it reflects the correct order
of magnitude.
Update stats, phrasing in sexual/domestic violence slide
Tweak tense agreement in DUI slide
Remove repeated phrasing of text about the data request
