Reactions to the malt liquor study

One University of Minnesota study says malt liquor could be factor in higher murder rates. According to MPR's feature,

[Principle investigator Rhonda Jones-Webb] said malt beverages are associated with heavier drinking and aggressive behavior. She says that could contribute to higher homicide rates in African American communities.

"I think what factors in is WHO tends to drink malt liquers. now...wouldn't that be kind of like profiling?" - anna g. vanwinkle

"Use of alcohol or drugs leads to higher murder rates and other crimes in ANY community." - Jim G.
