The reports I am reading this AM. confirm this was not a Tea Party person.
Regarding your report at top...This is the story being setup as what is being prepared as the story to report. There is no doubt this was a person of the left due to the confirmation of such. You have the analysis correct, at top. This will be the main topic to deflect this person (Jared Laughner) being a leftist. Too many people attempted to blame the Tea Party, now they are running for cover as the truth is coming out. Side Note...Blue Boy does not appear to be Laughner.
Side note: BoyBlue, or whatever the nick, does not appear to be involved. Not confirmed as of yet though. More digging is required.
second correction Laughner should be Loughner
