It happened fast. Thank goodness it wasn't in the typical "under the counter" situation you hear about so often. The shots seemed a little errant into the cooler there, but the affect was quite obvious. The threat was immediately driven away. I'd like to see this happen more often.
The alternative is something like this. Seems to be effective in his scenario (though not the best option). Lotta anger there. I give props for the fight in the dog on this one.
