HOBART, Ind. (CBS) A northwest Indiana couple claims several officers roughed them up in their own front yard, and they say it was all captured on this surveillance video.CBS 2 Northwest Indiana Bureau Chief Pamela Jones reports in surveillance video, a woman's head can be seen snapping back. Her attorneys say a police officer punched her, then took her down in her front yard."I was shocked when I saw this. And I grew up in Hobart," attorney Ron Layer said. "I can't imagine what any woman could say to a police officer to cause him to take his gun out and point it in her face."There's no audio in the surveillance footage, but the Olig family's own surveillance camera perched outside captured police arresting the mother, father and two sons August 30, 2007.The Oligs' attorneys say those arrests were unprovoked"There's no assertive moves by any of the Oligs against any of the officers before there's this punch by one of the police officers into Candace," said attorney Michael Babcock. "It actually knocks her to the ground."Police reports the attorneys gave us tell it a little differently.Corporal Paul Oliver states the wife, Candace Olig, came at him with a closed fist and hit him on the head three times, that he pushed her backwards in the chest, and that he pulled his handgun and pointed it towards her.Attorneys say the video disproves those actions."Even once the melee kind of starts, with the officers grabbing each one of the Olig families, throwing them to the ground, you still at no point do you see them resisting at all," Babcock said.Hobart police tell CBS 2 they've been called to the house on numerous occasions, and some neighbors say domestic turbulence inside often spills out onto the street."It's all the time; always got the Hobart police over there," said one neighbor.But this time, attorneys say the police were causing the turmoil, even when the husband, David Olig, tried to lead his family to back away.The Hobart city attorney said an independent investigation is being conducted by the Lake County Sheriff's Department.
