Disorderly conduct and obstruction charges have been filed against a Milwaukee man who says he wanted to “play super-hero.”  Matthew Hughes told W-I-S-N 12 News he jumped on the suspicious backpack in the city’s downtown area May 12th to save people.  Hughes told officers he had been watching the incident on television when he got on his bicycle and rode to the scene.  With members of the bomb squad and police officers nearby, he grabbed the backpack and dumped its contents.  There was nothing dangerous inside.
