Skew you are the one with no clue, read your post, you are not able to defend yourself. I believe you have fallen into a great trap, you were called because the homeowner did not like the first answer they got, you furnished the answer they wanted and then did the work. In court this will be a major question put forward, as will your education, training and experience. I imagine you will also be asked about what you did to verify that the trees you worked on, you had permission to work on.
Skew you have refused to read and understand what has been said in this thread. BUt most unfortunate is that you may have removed a tree from a property that you had no permission to be on. I would advise you to call your insurance and your lawyer, unless of course you do not believe in private property rights.
Get ready, because if you think that I am harsh, just wait till you have to defend your work, your competence, your education, your training, your specific tree hazard assessment training and knowledge,, your ethics, your integrity, your report on these trees and your business practices. All this will be tested in court and public.
