Hey Walter, it wasn't the pigeon’s fault that the rocket nearly destroyed the city.
Here are my reasons why it is your fault.
Firstly, you were careless! You left the suitcase open for the pigeon to fall in. It wasn't an ordinary suitcase, it was an undercover case so you should have been more careful.
Secondly, pigeons are not smart. For example, pigeons can’t read and they don't have a big brain.
They only have a very small brain so it was just pecking everything because it was dumb.
Lastly, he only wanted the bagel because he was starving. He had nothing else to eat so he went for the bagel in your hand.
Walter I think it was your fault that the rocket went off and the pigeon did not deserve to be killed.
