Would mod up if I had points...
Just remember that the yahoos cheering Trump's comments don't speak for all conservatives. While around 3/4 republicans currently "approve" of Trump (a pretty low bar, but it's a disappointing figure nonetheless), there are quite a few conservatives like myself who are vocally opposed to Trump and his attacks on personal freedoms in this country. I hope he gets prosecuted for this.
I agree that more training for those who want to carry firearms would be good, but gun owners rightfully fear more gun legislation. The government has a history of badly implementing good intentions when it comes to gun law.
