- Does the government have to show that the speaker recognized it was quite likely to be perceived as threatening, and ignored that risk (generally called "recklessness")?
- Does the government have to show that the speaker knew it was nearly certain to be perceived as threatening (generally called "knowledge")?
- Does the government have to show that the speaker specifically had the aim of making people feel threatened (generally called "purpose")?
