Apparently, you're leaving out words from what I stated, and imagining a point of view of mine that isn't true.   Certainly, something's wrong with the level of violence in our country.  I don't think it's fair to distinguish the difference among any forms of lethal weapons though, especially the difference between "assault weapons" and other guns.
Since you believe that I meant we should do nothing about violence, you missed the point altogether.   The focus on assault weapons is meaningless.    They're an insignificant blip in the number of homicides in this country.  
If we value life, then the focus should be on saving lives, not stopping something that we have an incredible lack of control over.   A murder is a tragedy.   A 2 year old drowning in a 12" deep inflatable pool in the background is no less a tragedy for those involved.  With such an enormous focus on "assault weapons", we're psychologically creating the illusion that the problem of assault weapons, and the problem of school shootings is much more frequent than it really is.   (And diminishing the consideration of risks that are currently present.)  People are becoming vigilant about the wrong things.
So, we want to hire armed guards for schools.   We want to put in metal detectors.  And so on.   First, Columbine had an armed resource officer.   He was in his car, eating lunch, watching an area where the kids go to smoke.   He was fired upon within 5 minutes of the shooting starting at the school & was completely ineffective in stopping anything from happening.   If you look at the amount of preparation that Klebold & Harris did (distractionary timed bombs off campus), I don't think it's outside the realm of reality that they accounted for his lunch time.     Connecticut: locked doors.   These things did nothing to prevent tragedies.      Meanwhile, all the deaths from school shootings combined since Columbine still don't add up to the number of people struck annually by lightning.    How many schools have lightning detectors for their sporting events to detect lightning in the area?   An under $200 device that could be more effective at preventing deaths than anything suggested after this event by people using emotion vs. statistical reasoning.
