If it’s true, as someone else posted, that she used toilet bowl cleaner and balls of aluminum foil, then it is no accident. That is a well-known recipe for a crude homemade bomb, available all over the internet. Nobody accidentally combines those two things on a lark.

"If it’s true, as someone else posted, that she used toilet bowl cleaner and balls of aluminum foil, then it is no accident."

You haven't seen so much as news of any good evidence or testimony that it wasn't an accident. And the news media are often hysterical and incorrect.

"That is a well-known recipe for a crude homemade bomb, available all over the internet."

It's not well known, because most people aren't interested.

"Nobody accidentally combines those two things on a lark."

People combine all kinds of hazardous mixes without knowing what results will be.
