When Will The Parents Of The Trump Shooter Be Arrested?

Charging parents for the crimes of their children, is an obvious, veiled attack on the second amendment. Is charging parents for the crimes of their children only reserved for those people that shoot up schools or can the law be tailored universally? I bet the parents in Chicago, must be quite nervous right now. When are those parents going to be arrested for all the shooting being committed there?

More on topic, did the Trump shooter use a rifle, belonging to his parents, or doesn't it matter? Who can take the US judicial system seriously any longer? These people are corrupt partisan operatives. Societies being run like this one, can't survive much longer.
