Okay, hang on. You want this website to tell you how to be a lawyer? Let me answer in your chronology.
According to the Rules of Evidence, circumstantial evidence is to be given the same probity as direct evidence. (This is not TV). There are certainly nuances to understand but how can anyone give you knowledge and experience that has been obtained through at least 3 years of law school, studying for the bar exam and, most importantly, trying cases in court?
Next, the court is under no obligation to provide technology for you. Some may be wired up and ready to go but most are not. You can certainly ask, but you may need to bring all of your own stuff and set it up yourself. (This is what law firms do. We provide a service and assets which allow us to defend you professionally and efficiently).
Let me put it another way. If you have a cracked and abscessed very painful tooth (and no dental insurance) would you go down to your workshop and yank it out yourself with no anesthesia, pain medication or antibiotics? Of course not! You would find the money somewhere and go to a dentist to have it done right.
Another example; if your car breaks down because of a blown transmission or cracked cylinder head and you absolutely needed your car for transportation would you fix it yourself? (Maybe, if you had all the knowledge, tools and parts).
See where I am going? If the case is truly important to you, hire an attorney. If you can not afford one, the court will ask you why and provide you a "public defender" if you qualify. And one more thing. If you represent yourself, the court WILL NOT give you any break because you are not a lawyer. You will be required to follow all the rules of procedure, evidence, and protocol like any other lawyer. If you do not, your case will be extremely jeopardized.
In summary, to paraphrase a common but true saying, "a person who defends himself in court, has a fool for a client".
This post is not meant to: 1) contain my signature; 2) contain legal advice; 3) create an attorney/client relationship; or 4) guarantee confidentiality.
You should really hire a lawyer or have a public defender appointed.
It is always difficult to grasp the full extent of any legal issue from a brief introduction to a limited set of facts. If you are experiencing a situation that needs legal attention it is always best to set up a consultation with an attorney and go over the facts in greater detail. If you decide to enter into a professional relationship with an attorney hours of research will go into analyzing your case, so please do not expect that anything posted here should be relied upon without substantial further review.
