Look guys, I just checked with several doctors, three lawyers and a couple of judges and they all say that there are many questions they get which they only have a partial answer for or no information about at all and must therefore use their professional judgment and experience to provide an answer so that the right way to handle either a legal or to a medical question is to include a clear and simple disclaimer whether you are otherwise qualified to provide and answer of not. 

In other words it is far better not to delete a question but rather to answer it to the best of your ability and then add a disclaimer even if you are sure your answer is one hundred percent provable by the facts. Otherwise you should simply leave the question alone and not answer it at all and instead remove the answers which do not include a disclaimer or may be contrary to facts. 

Also, no one can be held responsible for providing an answer to a question, even if a disclaimer is not attached, in any scenario where the answer or "advice" is free of financial charge. In other words, unless you require something of values in exchange for your answer or "advice" you can not be held responsible for what your answer is. 

This is of course not the case when questioned by a police officer or other official or officer of the court who represent the State and are seeking an answer on the State's behalf. If you choose to answer their questions then you are obligated by law to tell them the truth although you are likewise permitted to withhold an answer or to provide a disclaimer if you do not.
