What should the punishment be?

Life sentence. This was an attempted mass murder.

A young father of 4 died that exact way when 4 teens threw a large rock into his van window. He was on his way home from work and took a boulder to the chest. Died slow and painful. This isn't funny, jail time bare minimum.

Charged for attempted murder.

low iq negros at it again

I’d class that as Attempted Murder !! 7 years Prison before Parole !

He did this for what ?

Attempted murder of the driver, surely? In the UK, that can sometimes mean life imprisonment.

Never underestimate your opponent!

Exile or death. They can choose.
