Right, but it's not a stretch to see why a family would be upset that their kid was pulled out of class to be interrogated by police regardless of the circumstances.
Who gives a shit what the family thinks when they let someone plot a terrorist attack and build a fucking pipe bomb in their house without saying anything? That's not exactly something you can do without drawing attention. If I were the cops, I'd assume they were at the very least indifferent to that plot and would influence the teenager if present. Cops are absolutely allowed to questions kids without parents present in cases like this when the kid is not being implicated in the crime.
As people have said, nobody is saying the cops broke the law. They are stating that they understand why the parents are upset. It's very easy to manipulate a child. Not sure what you're trying to argue here.
Admiral does have a point though, I mean in the wake of a terror attack there's not much room to consider the suspect's family's feelings, only their rights. ---
