This moron was let off the hook.
It's a slippery slope and I almost guarantee this CRIMINAL would've gone to trial had the alleged burglars not been illegal immigrants (and maybe even if Horn had not been a white man). A loophole in the Texas law would've been found and the jury would've found that this vigilantism was taken to a criminal level.
