That doesn't stop people from panicking (e.g. "My stuff!") and attempting to break the lock. In the NTSB report, people were arguing with the flight crew over whether or not to leave their luggage during evacuation. Edit: I'll add that I was in a retail store (employee) that was evacuated by police, due to an armed gunman. People were still worried about the office chair or shredder that they wanted to buy. An officer had to basically get up on a counter, and hold up his gun and badge and say, "Everyone out! Now!" On the way out some guy was trying to ask me if we would be open later because he (apparently) really wanted to get this office chair he was looking at.
