Banksy targets Disneyland

A life-size replica of a Guantanamo Bay detainee has been placed in Disneyland by "guerrilla artist" Banksy.
The hooded figure was placed inside the Big Thunder Mountain Railroad ride at the California theme park last weekend.
It is understood to have remained in place for 90 minutes before the ride was closed down and the figure removed.

BBC:

Apparently Disneyland's security staff shut down the ride and removed it amid fears over public safety.

Were they afraid it would run amok and attack the train ?
