As long as strollers and large backpacks are allowed into Disney, it will be very easy to bring a knife or gun. Security has never given my tripod a second look, and my camera bag is always open, but they never remove my camera to see what might be under it. Last month I took a cup of coffee from the Polynesian on the ferry to the MK, I could fit a big knife inside if I wanted. Last year, I brought a Nautilus from Trader Sams into the MK, security looks inside the Disney bag, but they never look in the boxes. Anyone who feels safer, is now less safe, because they are paying less attention to potential threats.
