At the end of Zankyou no Terror's OP, a disclaimer is displayed. It reads:
This show is a work of fiction. Any resemblance to real people or groups is coincidental."
The disclaimer is there because the series depicts terrorist acts and whatnot, but:
Is this disclaimer something the team decided to put in order to safeguard themselves?
Or are there specific regulations that make them put it there, given the nature of the show?
Also, I'd never seen this type of disclaimer in an anime series before. Are there any other series that also have them?
