Lawyers won't let you talk for two reasons. First, because you don't understand the law, even if you are reasonable, you may be caught legally by the other party, which is not conducive to litigation. Second, maybe you didn't tell the lawyer what you said, which will make him very passive in stating the case.
There is a process between the defendant and the defendant in court, and you can't say whatever you want. A trial doesn't mean there will be a result. So if you think it makes sense, you can communicate with a lawyer after court.
