The massacre in Colorado

The massacre in Colorado film shocked many moviegoers who had purchased tickets to see the new Batman movie, so some theater chains hired extra security guards, but experts say it is unlikely that further measures be taken for alter the pleasure of going to a movie, concert or sporting event.
The massacre occurred on Friday night in Aurora, Colorado, during the premiere of the latest Batman movie, "The Dark Knight Rises", left 12 dead and dozens injured. Authorities say the attacker apparently went out an emergency door-to-assemble, which was then used to return fire before the hearing.
The attack emptied some parishioners, who had waited anxiously for the premiere of the biggest movie of the third quarter, according to some.
"I will be alert if I see something strange," said Charlotte Kimbrell, 27, in Illinois before the premiere. Surely I will sit in the back row, far from the exit doors. "
That was the same reasoning on Friday had some lovers of baseball.
"I think paranoia reigns after something like this, but I think mostly all they can do is examine your bags and hope you're not crazy," said David Karney, Michigan, which saw a game of the Detroit Tigers and Chicago White Sox. "Ultimately, if you're mad and want to do something, you will anyway."
That feeling is understandable after the attack, one of the deadliest in recent U.S. history, but the wise in security believe that changes in the stadiums, theaters and concerts after the terrorist attacks of September 11, 2011 have made these places are much safer.
