The facts are they put the gun in his hands.
Had he have not had access to a gun, he wouldn’t have had it with him and done it. Having the gun gave him the option of shooting people at school. He had the gun a matter of days. Within days of having it, he used it.
Theres no evidence to suggest he was trying to get a gun, off his own back. Or even had the ability to. He could not legally own one and may not have had the connections or ability to illegally procure one.
Had he have stolen a knife from their kitchen and they didn’t know, they likely wouldn’t have been looking at charges. Or at least lesser ones. possibly child neglect charges.
Had he stole a knife and they knew and chose not to inform the school even though he drew photos of a school stabbing, they would be facing charges relating to that. There’s absolutely no reason this boy needed access to a gun.
If you can’t see the difference in parental responsibility between parents giving their child a gun and a child stealing a knife, there’s an issue.
Plus the whole ‘what’s the issue with guns. The Uk have stabbings’ is a weird comparison. How many stabbings in schools have we had where multiple people are dead and more injured?
How many stabbings in the Uk per capita compared with shootings and stabbings per capita in the US?
