It is interesting to see various Constitutional Law Professors and pundits discuss Sotomayor's role. Compare what Rebecca Rosen says here with what Jonathan Turley says here http://jonathanturley.org/2012/01/23/supreme-court-unanimous... or what Orin Kerr says in many posts but especially here: http://volokh.com/2012/01/23/why-did-justice-sotomayor-join-...
Also interesting the comparisons of the roles and opinions of Alito and Scalia.
Another relevant article is this one: http://www.wired.com/dangerroom/2012/01/homeland-security-su...
Homeland Security wants technology to persistently spy on 4 square miles (of city) at a time, with automated, real time, motion detection."
Think about that and whose Jones opinion you prefer....
