to be more accurate you should compare european countries with american cities

You think so?! Please point me to the US cities with populations of 80 million (Germany), 65 million (France or the UK), 60 million (Italy) or 45 million (Spain) then. Oh, and those five countries' total population - roughly the same as the US. I hope this takes care of your sample size concern here...

also...if you remove the dhmikratic controled cankers from the US data
such as chiciago, baltimore..etc.

Do you mean that there are factors that are way more important than gun proliferation like poverty, bad governance and so on? Then I agree completely.

then the US is the safest place on the planet..

You would have to cherrypick the hell out of the data for it to support that claim as the crime rate needs to drop down orders of magnitude, not just a bit for that to be true.

that might be why there are so many people trying to get here.

For people not from the most developed parts of the world, all of the developed countries including the US would be a significant improvement on safety. Other important reasons for people to be trying to get there are opportunity and liberty. For a lot of people it's really a place worth getting to.
