But I found that the Texas bill just clarifies that existing Texas "self-defense" law also applies to teachers on the job - a clarification that doesn't really seem to be needed, although one would have to look to how the courts have actually applied the existing law
(If you read it, note that each section of the bill laying out the availability of the self-defense rule cross-references existing Texas law as applicable to teachers.)
OTOH - to the extent that Texas law already allows use of deadly force to defend property strikes me as pretty strange values.
The existing Texas law is what should have people alarmed, IMO.
