You are looking at this wrong, nobody is talking about killing the neighbors dog, they are talking about dispatching a nuisance animal. I don't really have "neighbours", but those around me are familiar with my dog as I am with theirs. When someones Else's negligence is affecting your day to day activities it is just a matter of rectifying the situation, and everyone would agree that having the dogs owner take responsibility for their pet is the NUMBER ONE choice, once that has been disregarded then it is up to the land owner to decide how to fix the situation.
Secondly, the liberals don't fear us, they fear guns, and there is no such thing as facts when it comes to how they think, our discussions mean nothing to them, they manifest facts, not research them.
