Banning -any- sort of semi-automatic rifle intrudes on the 2nd amendment.
Never mind that these are exactly the kinds of weapons protected by the 2nd.
2nd Amendment: A well regulated militia being necessary to the security of a free state, the right of the people to keep and bear arms shall not be infringed.
It says nothing "exactly" about assault weapons.
According to the SCoUS in
Miller and
Heller...
To be protected by the 2nd, a wepon must be suitable for service in the militia, part of the oridinary military equipment in common use at the time, and suitable for any of the traditionally legal purposes one might thave for a firearm.
There is no better specific example of this sort of weapon than the M16/AR15 platform and no better general example than an 'assault weapon'. It is therefore impossible to soundly argue that 'assault weapons' are not protected by the 2nd.
The classic "fire in a theater" limit to free speech is considered Constitutional because, although it does abridge freedom of speech, it can hurt innocent people;
No.
The 1st amendment does not protect it because it places people in a condition of clear, present and immediate danger; similarly, the 1st does not protect slander and libel because they actually cause harm. We do not limit the exercise of a right, any right, because there is some possible potential for harm - because "it
can hurt someone" - we limit it when it causes actual harm or created the previously mentioned condition.
The same applies to the 2nd Amendment. We can limit gun ownership (not take all guns, not ban them all, just some) and still be true to the Amendment.
For
the same to apply to the 2nd amdendment, you have to show that simple posession/ownership of an AR15 harms people or place them in a condition of clear, present and immeduate danger; if you cannot, then your example dioes not apply and your argument fails.
I look forward to your deminstration as to how simple posession of an AR15 causes harm or creates that condition; I further look forward as to your argument as to how an AR15 does NOT do this once you remove the bayonet lug and flash suppressor.
