The 2nd Amendment is meant to protect Citizens from the government.  It isn't meant for hunting and has nothing to do with the technology employed.  Taking the means for such protection from Citizens does nothing to stop crime or the horrendous school attacks.

If you're serious about protecting children, then fortify schools like we do banks.  Protect our children like we protect Politicians and Celebrities.

Ensure that those identified as dangerous to schools get help and have wellness checks.  

Disarming the MILLIONS of law abiding citizens isn't the answer.
