Semantics, I know, but it wasn't an AR-15, it was an "AR-15 STYLE". Not sure why the actual rifle wasn't mentioned, other than a picture that was tweeted out.
I've said before and I'll continue to say, as for gun control and laws, what is needed is UNIVERSAL laws. I'm from Massachusetts and they have some of the strictest laws, while other surrounding states are more relaxed. Other states have little to none. Drivers licenses are universal, so should LTC's.
And why doesn't the other common denominator ever get mentioned (other than "assault rifle/gun)? Terms like "loner", "anti-social", "no friends", "didn't fit in"..... the list goes on. Many are quick to blame the tool, but not the tool handler. I also don't understand why any other type of "mass killing" never get the same attention or discussion? There was one recently that was outside the US, and didn't involve a gun (no AR or any other type of firearm). It was posted here but only had a handful of replies. No hate, no anger, no cries of government needing to do more, nothing. Why? Are only certain tragedies worthy of discussion and outcry?
I'm sure I'll get blasted for this, so be it.
Edit to add: it was a mass stabbing in early September in Saskatchewan, Canada.
