The son is not a victim he was engaged in illegal selling activity. He made boasts of large amounts of cash in the home and drugs. 

This is why most successful drug dealers use banks and wash the money.  Most people don't want to put a huge target on their back.  I imagine that's why he had all the cameras set up at the house.  Though it didn't save his moms life. 

Any idiot boasting of having large amounts of cash at home is saying "hey criminals I'm an easy target, why try robbing a bank when I'm so much easier"

Just stupid! He was dealing out of his damn home. His criminal stupidity is what made him a mark and got his mom killed.  Condolences that she passed but this is not victim blaming.  He's as much responsible for his illegal sales and bullseye comments as the stupid thugs who showed up to rob him.
