Why didn't they FIGHT??!!!

This is just sick. (Please note that due to the nature of this story, I will break my usual rule of no profanity. And there will be yelling. Lots of yelling. There is just no other way to accurately get my feelings about this, and my point, across.)

Officials said Monday that 27-year-old Sergio Casian Aguilar parked his car on the country road Saturday night and proceeded to stomp, kick and punch a 2-year-old officials believe to be his son.
and
Passers-by called 911 and attempted to intervene. Dan Robinson, the chief of a local volunteer fire department, says he got out of his car and tried to stop Aguilar, whom he described as having a "total hollowness in his eyes."

He was finally shot at the scene by an officer responding to calls from bystanders. The original version from this morning is gone, and Yahoo! news doesn't seem to have a way to find it, but it mentioned that the first witnesses were an elderly couple who called 911, and that 2 or 3 other cars stopped with people calling 911. Although both stories mentioned people trying to stop him, neither mentioned any physical altercation, or anyone getting hurt trying to stop him.

The first thing I thought when I saw this was: Why the hell are you bothering to call 911?! When yelling at him to stop didn't work, why the fuck did nobody try to FIGHT him. He's beating the shit out of a 2 YEAR OLD CHILD for God's sake!! I know this is Kalifornia, so shooting him was probably not an option for these people, but even the elderly couple, if they can drive, they can swing a tire iron at his head from behind! There were 3 or 4 cars there, meaning at least 3 or 4 people. Dogpile the son of a bitch! Don't just stand there with your thumbs up your asses waiting for the police and watching a 2 year old child get beaten to death!! STOP HIM!!!!!

What's worse is the fire chief. Dan Robinson, you are a worthless piece of SHIT! You didn't "try to stop him," you tried to talk to him. He was beating this kid bloody. The story this morning said the child was so badly beaten that they were going to have to use DNA to identify him! If you're an active fire chief, you are not a 90 pound weakling. If you are? You're in the business of saving lives. As a volunteer. GRAB A TIRE IRON!! Hit him with a fire extinguisher!! Do something, DON'T JUST FUCKING STAND THERE!!!!

Even if he beats you senseless, even if he breaks every bone in your body, even if he kills you, protecting an innocent child is worth it. When he's beating you, he's not beating the child. If you last long enough, the police that the other useless cowards called will get there. Even if he finishes with you, you've bought the child some time.

There are some things worth fighting for. There are some things worth being injured for. There are some things worth dying for.

Stopping something like this is one of them.
