I am not at all familiar with Texas State statute.
As an example of the places with which to be familiar, here is the SC State Statute web site
in re Texas, I found
http://tlo2.tlc.state.tx.us/statutes/index.htm but have no more notion of how to use it than to charge ahead blindly.
I would be aware of the different types of law with which we deal, common law (in some jurisdictions the Napoleonic Code), black letter statute law and case law stare decisis; and of the different jurisdictions that may have relevant law, the Feds, the State, the County and the County's political subdivisions.
The frequency of the challenge to citation has diminished somewhat here.
Best wishes and welcome to one troubling to be a good researcher.
