I was wondering about this, too, Sandy. If the man had a previous history of violence and shooting a gun for no reason

you'd think they'd take precautions....like ummmm...I don't know...
take the gun away!!
We have a 88 year old lady here in Atlanta accused of killing her boyfriend over a love triangle - she caught him with another woman!! And shot him! She's been going back and forth with retrials, etc....I know she's 88 but it's obvious that it doesn't matter what age someone is when it comes to using a gun...they kill no matter who's pulling the trigger.
For the victims family's sake I hope they take this man off the streets and get him the help he so obviously needs.
