I'm just surprised I seem to have read that having a few drinks somehow negates your right to self defense in a public place.
From Chapter 9 TPC:
was not otherwise engaged in criminal activity, other than a Class C misdemeanor that is a violation of a law or ordinance regulating traffic at the time the force was used.
In other words, if you are engaged in criminal activity( Class “C” traffic offenses excluded) your legal justification for the use of force is not there
Public intoxication, walking by legal 06/07 signage, jay walking, etc.
