I can't see why his momentary behavior is any less indicative of his character than his murderer's momentary behavior in killing him.
My focus on his from the beginning has been deliberate because this forum has a predictable pattern of rants in the gun control debate. Of note, the bigoted snark by Access just now involving Texas, as if the vast amount of guns in this country are concentrated in "redneck" states.  So, Chicago is a redneck epicenter?  And LA?  Sooo many more senseless murders are carried out every week in thug-on-thug petty conflicts, but the forum is deadly silent about those, as they aren't in the zone of ire that we reserve for the PC topics of choice. 
Just as many posters here have that pre-set bias against Florida or Texas, I share a lack of care about assholes who selfishly assert their individuality in a room of 300+ people who gathered to see a movie on a big screen in the dark and paid to do so.  It was egoism plain and simple. All the sentimentalism about his daughter is irrelevant.  He could have been texting to Grindr, the IRS, or President Obama, and it doesn't matter.  His behavior was what it was, and the notion that "yeah, but the little girl was so CUUUTE is just daft."
No one deserves to be killed for such an selfish act, but no one deserves to be clothed in white either.  He was a selfish and uncaring jerk.  Now, he's a dead jerk.  I didn't ask for him to be killed. I didn't applaud his death, but I have no more obligation to care about his murder (beyond upholding our laws) than you do to care about some kid who joined a gang and got shot by another gang member on a street corner in a drive-by killing. 
Despite tireless efforts to recast Jayhawk, DonQuixote, myself and others into a vigilante mold, none of us have advocated gunslinging.  Plain old vendettas, as always, prevail here.  Telly obsesses with his newly-found bold function and his disgusting pearl-clutching.  What a poor job of acting.  His choice to ignore all others arguing the same point is the evidence.  These see-saws are simply excuse du jour to pick up the battle axe and head back to the field to hack away. 
The predictability of posts in the "what Jubbers look like" thread during such episodes is even more predictable than the threads themselves. We have institutionalized the bathroom stall graffiti in Hot Topics.  How like gay high school.
