有關“闖紅燈”上庭後的問題

去年八月吃了張闖紅燈的罰單。當時警察說我在紅燈時開過traffic light,  但是我說我是在yellow時開過的。她當時就說她有video。我就說我要看，她說她不能給我看，但是可以到法庭去看。所以，我今天去去了法庭，警察也來了。我陳述了當時的情形和對話，法官要求警察出示video.警察說她今天沒有帶來，並且說因為是tape, may take a while to get it. Then the judge asked how long it may take, the police then said might be a week. After that, she changed her statement saying that the video may not include the first 30second, that means the video can not show the time I drove into the traffic light. I insisted to watch the video, then the police said she did not have it because she did not record, blablabla. At the end the judge said he needed to review the case and get back to me by mail.

在回家的路上，我越想越不對勁。我當時應該堅持說，如果警察沒有她當時所說的證據，出爾反爾的，那the case should be discharged.

我現在想請問，

1）我是否可以在收到法庭的裁決前，再寫封信進一步闡述我的觀點呢？因為我可以看出來，法官站在警察一邊的。

2）如果收到裁決後，是否還可以appeal?

 

多謝了！
