I do find it interesting that you have narrowed your search in such a way that it presents the conclusion you want. That is the primary protest of many people here. The only way the data presents this possibility is if you limit it to large urban centers. If you begin to narrow it by small urban centers, by state or my political region it tells a very different story. Wanna guess which states have the highest murder rate in 2015 and how they voted? Don't bother, I have you covered:
By the very same website you cited I simply expanded the scope to state and would you look at that. I even used the same ratio (per 100,000 people). But you don't want to talk about this. Why? Because now, all of a sudden, the political bias has shifted in favor for the party you are seeking to demonize. I can sit here and play with this data to get any conclusion I want. Bottom line? This OP is a lazy attempt to polarize a discussion under the guise of something better. Thankfully, most posters here have seen through it.
You are missing a critical element in your chart when you go to the state level. The demographics of those committing murder in those states, and the locations that those murders are being committed.. That data will take us right back to square one of the OP.
