The US surpassed 12,000 gun violence deaths and will reach 50,000 verifiable incidents by the end of the week. You can go to www.gunviolencearchive.org to see a constantly updating Summary Ledger and a searchable database of the toll of US gun violence.
I should also add that there was another siege in SE Pennsylvania which didn't make US MSM, where at least 6 people died. I believe all the victims were armed as well.
It's news when it happens in Australia, but another day when a mass shooting happens in the USA.
