Suspicious activity at California shooter's home not reported due to fear of racism.

Well, there are two ways this scenario could go wrong. They are innocent and you accuse them of something and sound racist in doing so. Or, you could not say anything and they do turn out to be terrorists and then you've got fourteen dead.

So, you can choose to save face at the risk of fourteen dead, or you can confront a potentially innocent person and possibly look like a racist asshole.

It seems pretty clear cut to me.
