Following the Aurora, Colorado shooting at a midnight release of "The Dark Knight Rises," there have been a number of different reactions and steps taken to stay respectful in the wake of the tragedy. Earlier this week, DC Comics announced it would be delaying "Batman, Incorporated" #3, which was set to hit stores on Wednesday, while Warner Bros. pulled its weekend radio and TV spots advertising the film and donated a "substantial" sum of money to charities supporting the victims of the incident.

Today, The Chicago Sun-Times reports the Lurie Children's Hospital in Chicago has cancelled an appearance by Batman, concerned an appearance by the hero could upset children and parents. The Batman in question is Lenny B. Robinson, a Baltimore businessman who visits sick children dressed as Batman in a custom-made Lamborghini Batmobile. Earlier this summer, Robinson went viral on YouTube as the "Route 29 Batman" after getting pulled over in his Lamborghini dressed as the Caped Crusader on his way to the hospital to visit sick children. The independently wealthy Robinson planned to visit children nationwide this summer and spends over $25,000 every year on Batman-related items to give to sick children.

"This senseless act of violence has nothing to do with the Warner Bros.' Batman franchise," Robinson said in a statement following the shooting. "At the heart of the movie is a central heroic figure that gives hope. The shootings in Colorado was a tragic event, but will not stop me from portraying Batman. I will continue to portray this iconic superhero, giving courage to sick children around the world that need it most."

Of course, there is also some positive news springing from the tragedy. "The Dark Knight Rises" composer Hans Zimmer, who wrote a composition called "Aurora," which Warner Bros. revealed on Facebook earlier today. 100% of the proceeds from digital sales of the song will be donated to the Aurora Victim Relief organization through GivingFirst.org, a program of Colorado's Community First Foundation. The minimum donation to download the orchestral score is $0.10, with tiers going all the away up to $2500.
