What I am wondering is whether Texas law authorizes a home occupant to point a firearm at a verbally irate person who does not leave his property upon the home occupant's request, because the issue of who is the aggressor could be determined based on that point rather than at the point where dad goes after the shooter. If home occupant was legally justified to point the gun, dad was the aggressor.
As indicated in the Texas Laws video posted, AFAIK it is legal for the property owner to point a firearm at a trespasser.
