Bad guys

Here is a good example of what is wrong with this country. In my childhood days, this would have never happened like this but if the assailants were THAT belligerant, then they would have simply had a knock down drag out fight with the person trying to intervene, but come back and kill him? FOR WHAT? What the friggin' hell did that prove except how stupid and ruthless they were. There are just too many such incidents these days. Recent shootings in San Francisco have happened in the 5th and Mission garage and at Fort Funston. It seems like there are less and less safe places in this crime ridden city.
