Instead of knee jerk reacting &amp; blaming inanimate objects for the actions of a troubled individual (yet again) ask yourselves 2 things: 

1) Why do the mentally ill seemingly have such easy access to weapons if known to have said issues?

&amp; 

2) What's really wrong/going on within society today/these certain areas that shootings occur in for the ill to choose to react to their problems with weapons in the first place?
