I am a retired police officer of 35 years and have been to court a few times needless to say. Attorneys can turn things around if you give them too much information. In court "black is black and white is white" and don't add any coloring to it. That is what I learned 35 years ago at the police academy training. You can only testify to what you know and not what the other inspector knows. You can't contradict what he did because you are not aware of his knowledge base. You can only testify to what your knowledge base is and thats all. The definition of an expert is knowledge more than the average person or layman has through training or experience. Don't fall for the statement "in your opinion is the man right or wrong" because if they asked for my opinion I would expound on everything I knew about form baseball to eating late meals. In other words don't give th attorney any fuel for his fire because he is an EXPERT in turning things around to benefit his client. Also if it is a friend of yours tell the attorney you are bias in you opinion of your friend and you feel it be in your best interest to not get involved. Jet away Forest Jet away as fast as you can. Money can't replace friendship or a good working relationship. Good luck.
