LILY.
They are fucking children, they're just more dangerous and obviously less stable. Helping is one thing, these people just threatened a stranger without provocation. They don't need protection, they need to be put away. I don't care where they're from, I do know that they've been here a while and if they still act like this then they're not trying hard enough.
We've all seen horrible shit, there's no excuse for this. Not in front of kids. No excuse.
