A few weeks ago, when news broke of the Boston Marathon bombing, how many of us put that event in a local context? How many of us imagined another bomber living somewhere in rural Minnesota? That thought came to mind Tuesday, as I read about the arrest of a 24-year-old potential terrorist in Montevideo. Authorities say the arrest and confiscation of bombs probably saved lives. Tuesday's Star Tribune story said authorities searched the suspect's father's home and found more than a dozen bombs inside a shed. Authorities described some bombs as being sophisticated and others were packed with shrapnel and nails. This is a shed that sits just outside a town about the size of Windom - a community 100 miles north of here. Based on Tuesday's story, there were signs that this guy was a little off. A neighbor recalled hearing the suspect talk about "white supremacist stuff." He flew a U.S. flag upside down (an anti-government sign) and spray-painted "B.S.M." (Black Snake Militia) on his father's home. The world is changing, folks. Bombers don't just live in Boston or New York. When the signs are there, we need to be wary.
