>For example, the San Bernardino killers apparently took out a massive loan and emptied their bank accounts prior the attack.

This happens quite frequently when people are going to make a big purchase or pay off another loan with worse terms. It's not as much of a red flag as you would think.

Sure, but taking out a massive loan in coordination with other signs, like buying guns, would start to paint a better picture.

Problem is, the police seems to be spending the resources that should be monitoring those people on monitoring everybody.

But coupled with the stated other red flags, this one is bright red with big red arrows pointing to it.
