I'm not familiar with that institution so I might be committing a blunder here, but their reporting seems incredibly biased for a "research" institution, and I can't help but wonder what methodology they're using to classify their data.
E.g. take this article: http://crimeresearch.org/2016/01/compared-to-europe-the-us-f... . They're mentioning:
- 303 deaths in the EU. This is simply an incorrect result, it counts victims from Norway, which is not an EU member.
- Only 4 mass shootings in the US in 2015. I don't live in the US and I can name at least 6 that made the headlines over here in Europe (e.g. the Harris County mass shooting isn't included).
- Hundreds of victims in France -- which is correct in terms of numbers, but most of them were victims of terrorist attacks, not mentally-deranged students who bought a rifle one sunny morning and started firing around. Most of those incidents barely match their own definition: "four or more people killed in a public place, and not in the course of committing another crime, and not involving struggles over sovereignty".
- A high number of victims for Norway, all of which are due to the Breivik incident. Limiting the debate to the Obama administration has the convenient consequence of keeping Norway's figures high. It would literally be twice as low if it were to include the Bush administration as well; I suspect the figure for the US wouldn't be twice as low in that case.
Besides, the conclusion is highly debatable. It tries to obtain that "US becoming safer compared to Europe" but:
- It does not include data from all European countries
- It "statistically" (i.e. incorrectly) conflates countries with widely differing legislation and enforcement status. This is very blatantly wrong: Serbia, second in that list, has a very strong gun culture and very liberal gun ownership laws compared to other European countries. My Serbian friends can carry guns that are only issued to members of the police and military where I live.
I don't know enough about how things are in the US to challenge that institution's opinions on the US, but their analysis of the European landscape is shaky at best, betrays a very obvious cluelesness about European laws and Europe in general, and frankly, I think the numbers are nicely tuned to give useful statistics.
