I don't know, did the Wharton police go in hiding in the Texas brush and start plotting more terror acts against the citizens of the US? If so, then we should continue our focus on them, just like the 9/11 terrorists?
I will add this, when such police misconduct took place in 2007, it was a bad cop, or perhaps a bad local police department doing something stupid, for which the federal courts (as in the Castillo case) were available for redress. In 2008, the country elected a guy who wants to create a civilian army as well armed and powerful as the military, who cares not a whit for the Constitution or for individual rights, and who likes to use heavy handed tactics against his enemies. Police departments nationwide are becoming more and more fascistic, especially those in big cities controlled by democratic machines who support Obama's fascism. They are sending swat teams out on routine warrants, shooting dogs first thing, and breaking down doors in an apparent effort to cow the populace. That is a trend that has grown exponentially since January 2009. An incident in 2007 seems to me more a one-off, a tragedy, but not a trend, something to be reported like anything else stupid people do. Billions of bullets to all the federal agencies, refusal to prosecute Holders' people, use of government resources to create an atmosphere of fear, that is the trend. This story is not part of that. Just a tragedy from 6 years ago. Might as well ask why we haven't heard about Chelsea King.
The unlawful and unconstitutional intrusion of government employees is not a “tragedy” but an assault on liberty.
A miscarriage of a child is a tragedy.
A government employee executed home invasion is an assault on the constitutional liberties of the victims.
