One could probably trivially combine the gun ownership data with publicly available property value data to pick targets for robbery.
You could further enhance it with proxies for use of security systems such as 911 calls (can one FOIA a list of all 911 calls?), but with the software industry as it is anyone going to all this trouble could probably make a better return by getting a job or just doing freelance dev work.
I thought that calls to 911 from security systems didn't happen directly. As I understand it, if a system is tripped, the security system's call center calls you, and in certain circumstances, would then call 911 on your behalf but not necessarily from your house.
Thats typically correct. My thought was that if you knew what numbers security monitoring companies would call from, you could filter out those calls, then extract the addresses they reported incidents at. Of course the monitoring company will filter out a lot of false alarms, so you'll get less data points to work from, so like I say... I'm not sure it would be worth it.
