Short-Term Benefits Of Limiting 2nd Amendment Rights

After the Florida high school massacre (As allowed by cowardly deputy sheriffs) there are those who would extend "infringements" on the individual and constitutional rights of:
1. Law abiding and presumed sane citizens who are 18 to 21 years-of-age by halting their right to buy the same long-arms as allowed older adults and continue the same violations-of-rights as now inflicted by not allowing them to purchase handguns or obtain permits/licenses to carry concealed weapons; Or,
2. Forbidding all, even older (Law abiding and presumed sane), citizens access to modern and effective firearms as allows them to defend themselves or innocent others---Especially when civil police are unable or (As in Florida or at the Columbine High School or a Florida night club) unwilling to do so;
3. The most common faux "Assault Rifles" offer our smaller and weaker fellow citizens (eg Women) a manageable and accurate weapon as allows them to defend self and innocent others from criminal attacks (eg "Home invasions as are often inflicted by multiple thugs and can require multiple "hits" to stop)

Those acts violate the very exact maxim given us by Founder Benjamin Franklin: "They who can give up an essential liberty to obtain a little temporary safety deserve neither liberty nor safety"!

Here, I note that there are "weapons of mass destruction" which:
4. Include trucks as might be used to murder children upon their mass leaving of schools at the end of each school-day;
5. Can easily (Without extraordinary technical abilities) be made from legally obtained materials;
6. Can destroy a large building (eg A high school building) or an entire residential neighborhood;
And,
7. I will not describe for obvious reasons.

Even the banning of all, civilian held guns (Or only semiautomatic rifles with large magazine)  would only be temporary safety. (Which efforts would likely begin an armed civil war).
