Why destroy Laketown's bridge?

[Rune Son of Bjarne]

So Alatar, lets say the watcher is unhappy with the number of dwarves he can eat at the gates of Moria. . . what does he do? For me it seems that these kind of creatures has a very limited habitat and no great possibilities of migrating.

It attacks Frodo first, but you and I know that the orcs of Moria had no idea the fellowship was comming therefor they could not tell the watcher what to look out for.

How do you suppose the master would keep it from everybody else that a humongous creature was living under the town? How would he "reason" with it and not reveal it? Anyways it needed not be bad for buisness if there was a Watcher that could be reasoned with, that would only increase the safty of Esgaroth and make it a better place for trading.

I appologise for not having quoted you in my reply, but it seemed like an awful work. . . . anyways In Conclusion: I am correct and win!
