Anna is absolutely right. You can also go to the city of Minneapolis website http://www.ci.minneapolis.mn.us/
and look up the crime stats for the particular area. They have maps that pinpoint where particular crimes have occured. You should also compare the stats of the neighborhood you are interested in with other Minneapolis neighborhoods as there are very few if none in major cities and surrounding suburbs that are absolutely crime free. Also remember that when speaking with the police, their opinion is biased as well. Their view of an area is always from the worst perspective as they deal 98% of the time with crime issues and don't have as good of a take on the good things happening in an area. Also, each area has a Community Crime Prevention Safe person assigned to it. That person interfaces with the community and can give you a more balanced view of what is going on in a particular area. You will find that contact info on the city website. You may also want to contact the community organization. Best of luck with your research.
