Do ya'll still hang cattle rustlers in Texas?
No, but this myth is perpetuated frequently.
Texas uses only lethal injection for executions. The only states that still have hanging available as a method of execution are New Hampshire and Washington.
Cattle Theft:
Less than 10 head; State Jail Felony; 6 months to 2 years in state jail; up to $10k fine.
More than 10 head; 3rd Degree Felony; 2 to 10 Correctional Facility; up to $10k fine.

Now, if the rancher catches you in the act and shoots ya dead...well, that's a whole other thing and Texas frequently lets folks off for this...or at least "fails to indict". I would think if he strung ya up though, that might get a different reaction from a Grand Jury.
