UPDATE: The owner of the theater has issued a statement to Consumerist regarding the situation:
You know that thing about there being no such thing as bad publicity? Well, it’s not true. Just ask the online retailer that is on the receiving end of Internet hatred after it posted a Tweet that made it look like the site was crassly trying to cash in on the deadly shooting rampage at last night’s Dark Knight Rises screening in Colorado.
By now you’ve likely heard about last night’s horrible shooting at a Colorado movie theater that left at least a dozen people dead and several times that number injured. In response, some theaters have already begun beefing up security for opening-day showings of The Dark Knight Rises.
