The first amendment does not protect 'speech' that causes actual harm (like libel and slander' or places people in a state of immediate, clear and present danger (like inciting a riot or falsely yelling fire in a theater).
This creates a perfectly good - and I would argue, as these limits are based on the precept that rights extend only as far as they interfere with the rightsof others, the the only legitimate - model for 'reasonable' restrictions on the right to arms, as they are eaxples of restricting actions on the bass that they lie outside the right itself.
So, again, I ask:
What's the 2nd Amedment analogue to yelling fire in a corwded theater?
To libel? Slander?
Fighting words? Inciting a riot?
