TUCSON, Ariz. (AP)
A gunman nearly unloaded a
semiautomatic weapon at a busy supermarket Saturday during a
public gathering for Rep. Gabrielle Giffords, wounding the
Democrat and killing Arizona's chief federal judge and five
others in an attempted assassination that left Americans
questioning whether divisive politics had pushed the suspect
over the edge.
The shooting targeted Giffords and left the three-term
congresswoman in critical condition after a bullet passed
through her head. A shaken President Barack Obama called the
attack "a tragedy for our entire country."
Giffords, 40, is a moderate Democrat who narrowly won
re-election in November against a tea party candidate who
sought to throw her from office over her support of the
health care law. Anger over her position became violent at
times, with her Tucson office vandalized after the House
passed the overhaul last March and someone showing up at a
recent gathering with a weapon.
Police say the shooter was in custody, and was identified by
people familiar with the investigation as Jared Loughner,
22. U.S. officials who provided his name to the AP spoke on
condition of anonymity because they were not authorized to
release it publicly.
The GCP event was set for 6 hours beginning at 10:00 am
local time in Arizona. The result is Chisquare 21730.969 on
21600 df, for p = 0.264 and Z = 0.632.
It is important to keep in mind that we have only a tiny
statistical
effect, so that it is always hard to distinguish signal from
noise. This means that every "success" might be largely
driven by chance, and every "null" might include a real
signal overwhelmed by noise. In the long run, a real effect
can
be identified only by patiently accumulating replications of
similar analyses.
