Quoting another THR member's post:
"That's what I thought also, but only at night?"
The color of the air does not matter! It is NOT legal to shoot someone for merely trespassing in Texas, day or night. There are indeed some other offenses for which deadly force may be used at night, but trespassing is NOT one of those listed offenses. Moreover, the use of deadly force must pass the REASONABLENESS test, something that is usually decided by a grand jury, though sometimes it is a trail jury that decides. There is no such thing as the right to automatically be justified in using deadly force for any property crime.
Really folks, read the whole statute, not just the opening paragraph or two.
