In most criminal defense cases, involved parties are given a chance to make pre-trial motions. These arguments serve a number of purposes, and they let prosecutors, defendants and legal teams define what can be addressed in the formal trials to follow.
Texas residents who stand accused of felonies may be interested to know that their mental health problems may not prevent them from being convicted. Although Texas is one of the states that allows defendants to plead not guilty by reason of insanity, prior cases, like that of Chris Kyle's slaying at a gun range, demonstrate that the argument doesn't always work. In that case, the defendant had already been diagnosed with PTSD and was being treated for schizophrenia, but jurors decided to deem him guilty of first-degree murder and hand down a sentence of life imprisonment.
