I own and have owned many pets,some dangerous, and it is the OWNERS responsibility to keep their pets and neighbors safe. Yes, sometimes pets do get out and when they do they are at risk and it is you, the owner that is responsible for that pets actions. Don’t blame the shooter, blame the owner for allowing his pit bulls to dig under the fence. It was not the shooters responsibility to fill in the hole the dogs dug. How can you be so dense to think the owner of these dogs had no responsibility in this matter.
Of course the owners bear some responsibility. So that justifies killing the animals? Bull! The dude was out to get the animals. I bear some responsibility when my kid hits a baseball through your window. You gonna kill him, too? Baseballs can cause serious injury!!
