You can also look at how over the past 20 years as gun ownership has increased in the US, violent crimes (including gun crimes) have continues to decrease - something Obama likes to tout.
So no, stricter gun control laws do not reduce gun crimes.
There is solid evidence against that point of view, and has been discussed/disproven numerous times. https://vimeo.com/97417009
The US is a special case compared to Australia, for sure, due to the massive difference in population. However many countries in Europe with similar population densities can manage low rates of mass shooting homicide via gun control laws...
True...
via gun control laws
... but this is unproven I think. Europe also has much better social security and mental health care, to name just a few confounding factors.
I do agree, to be honest
Another Harvard study concluded the same thing:

While American gun ownership is quite high, many other developed nations (e.g., Norway, Finland, Germany, France, Denmark) have high rates of gun ownership," said the report. "These countries, however, have murder rates as low or lower than many developed nations in which gun ownership is much rarer. For example, Luxembourg, where handguns are totally banned and ownership of any kind of gun is minimal, had a murder rate nine times higher than Germany in 2002."
You can certainly argue that gun crime rates are what matter, but don't confuse the two.
You respond to his cherry picking by suggesting a different cherry picking.
U.S. is pretty unique in many ways.
Canada had a school shooting this year[1].
Australia remains free of murder sprees since that one that convinced everyone to trade-in (or bury) their guns.
