There was no troll, it was a genuine question. One you failed to answer as well. Props to GFist for being the only one who tackled a possible answer (where there certainly are no clear answers).
That said, his comments about shootings in other countries not getting media attention the same way they do in the states isn't entirely accurate. I know when we have it happen in Canada it often gets international attention (such as the recent shooter in Moncton). The states might offer a different kind of attention, which leads me to what I believe might be partially to blame -- a culture of fear. I'm definitely seeing a lot of it in this thread, on both sides of the argument.
Also, I think Rok's numbers might in fact be correct. They seem to vary from source to source with a lot of shootings being labeled as gangland violence instead. It would come down to personal definition, I suppose. Can we agree more than a dozen is fucked up beyond belief?
