A、He had bribed the park keepers to keep quiet. B、People had differing opinions about his behaviour. C、The serious consequences

W: Mr. Stern, may I ask you? Do you think it was necessary and fair to arrest Steve Bril?
M: I don’t know whether you realize that this man has been eating up our park for five years. And he is encouraging other people to do the same thing every single day. [5] He’s been organizing groups to destroy our urban wildlife.
W: But Mr. Stern, this situation has been going on happily for five years. Why do you suddenly decide to do something about it?
M: [6] Well, at first we. just thought he was an eccentric person, a bit odd, you know. But over the years we came to realize that he is a dangerous guy. He’s been raining our city environment. Parks are to look at, not to eat. It’s just as if you’re going to allow people to walk through a zoo, and eat the baby bears.
W: [7] But surely you or your park keepers, Mr. Stern, could have discouraged Mr. Bril from his activity without going such drastic measures, without arresting him.
M: Steve is a nice fellow, but what he is doing is illegal. He knows an awful lot about wild weeds. [8] We’ll be very happy to let him organize tours if he. just wouldn’t eat the plants and wouldn’t encourage other people to do so, too. You never know what this could lead to, all sorts of people ruining our park in all sorts of ways. This kind of thing is very definitely criminal behavior and must be stopped.
