The only reason I brought up TV & video games is for the parents that don't talk to their kids. What bothers me are people that use TV as a babysitter for their kids and have no actual relationship or any discussion with them.
And here's the irony - I've been saying the entire thread that this was a parenting issue. People were quick to dismiss that and say, "we can't just fix parenting, we have to remove guns" When I offer: "we can't fix parenting, maybe we could tone down the violence and focus on mental health." I'm told, that's ridiculous - parents need to talk to their kids to discern between right & wrong. WTF ever... I give up talking to you people.
I'll summarize my thoughts once more. I personally feel that in instances such as this last week, the person is planning a large event to kill people and will use whatever tools available to do so. There are hundreds, maybe thousands, of methods to create equal or worse damage - that may not be as easily available for some people - but may be easier to get a hold of for others. Restricting guns will not stop what happened last week. The only situation I can see where gun restrictions might help are crimes of passion. Regardless of what anyone says, there are instances of guns being a successful means of self defense. You remove more civil liberties - people will rebel at a higher frequency. I wouldn't be surprised if harsh or extreme gun laws being passed wouldn't start a path towards anarchy - which is why a knee jerk/emotional response to this feels really dangerous.
