Already has in my book. They're against "high capacity magazines", none of which were used in Parkland. They're against "Assault Weapons", yet the largest school shooting for fatalities in the US was at Virginia Tech where the shooter had 2 pistols and didn't use "high capacity magazines". It's a false narrative.
If they really cared about crazy people getting guns, then they should direct their outrage to all of the laws that were in place that were negated by multiple government agencies.
The fact is they want to kill freedom by targeting the 2nd Amendment.
Who paid for the DC protest? That wasn't thrown together by some high school kids. Follow the money.
