IANAL.

Mischief is typically a serious crime; the legal and common uses of the word are different and confusing.

But I don't think Texas is restricting this to the more serious felony mischief here.

It ain't murder. (other words apply)

“Legal” murder makes absolutely no sense. If its legal its not murder. You mean “legally kill”

The alternative would be completely incoherent. If it's OK to prevent theft, the appropriation of property, it must also be OK to prevent criminal mischief, which is the destruction of property.

Note that the harm to the victim is identical in both cases, except that in the case of theft, recovery may be possible.

Yeah.

You expect pigs to defend you?
