The Best and Worst Cities in the US

So, reading my book it made me look over my shoulder a bit more actually. I don't have any past ex that's out to get me (Well, as far as I know), but I still get that sixth sense feeling sometimes. But which cities are the safest and really have no need to constantly look over your shoulder, and which ones are cities where you could get caught in the crossfire?
The most recent data I could find was from 2007, and it listed the top 25 safest cities and the top 25 most dangerous ones in the United States. Do you want to live in the safest town in the nation, where everyone has big green lawns, with big houses that look exactly the same, and all that jazz? Well the number one safest city in the US (as of 2007, keep in mind) was Mission Viejo, California. But don't worry if you live way over on the east coast, the list was fairly spread out over the entire nation-although there wasn't any mid-west cities in the top 25.
So, what city was rated worst in safety? And the winner is.....Detroit, Michigan! Woo Hoo!-wait, that's not a good thing. If you are currently living in Detroit, it might be a good idea to pack your bags and head to California. Actually Michigan seems like a somewhat dangerous place to live, because Flint, Michigan was rated number 3 in most dangerous place to live. But there were a few cities in Michigan that rated in the top 25 safest places to live. So it's a hit or miss I guess. Another interesting thing I noticed was that Kansas City, Mo. was rated 13 on the danger side, and Kansas City, Kansas was rated 25. So if you want to be a little safer, just head to the other side of the border, there's some barrier that keeps people more docile on the Kansas side.
Actually, now that I think of it, Micheal Moore did a documentary on firearms titled Bowling for Columbine. An interesting fact-Micheal Moore is from Flint, Michigan, so maybe he's a dangerous man? He also explain in the documentary that although Detroit is such a violent city, right on the other side of the border in Canada people are so unafraid of violence that they leave their doors unlocked at all times. Now, I've never been around Canada opening up random doors, so I have no idea if this is true, or in Moore opened many different doors and only put in the ones that were unlocked. Either way, I'm fairly sure Canada isn't as violent as the US.
