"...Its my job to keep between them and the predator..."

Very true. Now, let assume that one is driving down the street and sees someone else, kid or adult, in the jaws of a pit bull or rot. Now what do we do? I know what I would do, but I can legally carry a firearm...

Did anyone ever see that video of a Los Angeles County dogcatcher (female) with one hand and one breast in the jaws of a pit bull? Punchered her breast several times and crushed her hand. Neigbor guy tried to beat the dog off with a large stick, didn't faze the dog at all...
