Before the State can convict you of almost anything in Texas, it has to prove a culpable mental state. That principle lives in Penal Code § 6.02, and former prosecutor Brian Foley explains it in under a minute in this video.
The rule
Section 6.02(a): a person does not commit an offense unless he intentionally, knowingly, recklessly, or with criminal negligence engages in conduct as the definition of the offense requires. The four mental states themselves are defined in § 6.03.
When the statute is silent
Many statutes name a mental state ("intentionally or knowingly causes bodily injury"). Some do not. Section 6.02(b) says that if the definition of an offense does not prescribe a culpable mental state, one is nevertheless required unless the definition plainly dispenses with any mental element. And under § 6.02(c), when a mental state is required but not specified, the minimum is recklessness — intent, knowledge, or recklessness all suffice.
Strict liability is the exception
Only where the Legislature has plainly dispensed with a mental element — certain traffic offenses and regulatory crimes, for example — can the State convict without proving what you knew or intended. Courts read that requirement strictly, and a defense lawyer's first question in an unusual charge is whether the State has assumed strict liability where the statute does not actually provide it.
Higher proves lower
Section 6.02(d) and (e) establish the hierarchy: intentional is the highest, criminal negligence the lowest, and proof of a greater culpability constitutes proof of any lesser culpability charged. That is why a jury instructed on "intentionally or knowingly" can convict on evidence of knowledge alone — and why the defense must push the evidence below the line the State actually has to reach.
Why it matters in your case
Mental state is where most contested criminal cases are actually decided. Did you know the substance in the car was there? Did you intend to deprive the owner of the property, or did you believe you had permission? Was the injury reckless or an accident? As former prosecutors, Brian Foley and Luis Baez know how the State tries to prove what you were thinking — and how to show a jury that it cannot.
