You guys can't be serious, comparing an abortion to a mass shooting. An abortion is planned, carried out electively with agreement of affected parties involved. I won't debate the right or wrong of it.
A mass shooting is almost never planned and carried out electively with agreement of the affected parties involved, most particularly the victims.
The problem with guns: our laws forbid taking action when somebody knows something, or suspects something. The shooter may be a raving maniac or a quiet weirdo who people tiptoe around to avoid conflict; a misfit who threatens bosses or co-workers, especially after being disciplined or fired; a teen (the bully or one who was bullied) expelled from school after school for violent behavior toward teachers/classmates; someone with a rap sheet including bringing guns to school or work and expressing threats.
Between 1) a court system morally opposted to incarcerating/denying freedoms without solid proof--the proof that can only be...proven....after the mass shooting has occurred--and 2) privacy laws that threaten the livelihood of psychiatrists, clergy, counselors, and others whom a potential shooter may have confided in, if they bring their concerns forward (and still nothing would be done). I don't know the solution. JMHO.
