Looks like a good start.
Question: Does ODU comply location data in a mapped format? (I'll be surprised if they do not - it's a basic part of "community policing". :>) ) Or you could use one of those location tools from Google Maps that put push-pin icons on the map.
But if ODU is already doing the work, why are you replicating it? Can't remember the formal name of the "safe schools" law that applies to colleges, but all their data should be available just by going to their HQ and demanding a copy of their latest annual report. No need to even do it under FOIA. Then you can wade/weed through it to limit data to whatever specific crimes you want to look at. Heck, you might be able to get their data set electronically and just refine it from their own spreadsheet.
Putting a few more variables together visually could help greatly in changing the minds of some folks, or at least get them to start thinking about things.
