Hi again ema:
Only just spotted your last post: You and/or your partner may believe that the video evidence has been tampered with but not only is that an extremely serious allegation, how would you go about proving it, and who are you trying to say "tampered with it"?
Obviously your version of events will differ from the other side which doesn't surprise me one bit. Only the Court can ultimately decide one way or another. And put it this way, if anyone is found to be lying, for whatever reason, there is the possibility that they could be found guilty of perjury, basically lying under oath, a serious offence.
It would appear that the video evidence could be the reason why the more serious charge has been mentioned. What exactly have you been charged with? S.47 or S.18? It could make a significant difference were you to be ultimately convicted. And are you pleading guilty or not?
