After viewing the tape, Bourgeois made the determination that Gannon broke the law and had Detective Daniel Archambault arrest Gannon at the station, according to the affidavits. Police then went to the Gannon house and seized all of the video and audio surveillance equipment the family had set up in their home, including cameras, microphones and videocassette recorders, according to affidavits.There are two signs posted on the front and side of the house a little larger than the size of a hand that warn people about the recording. “Warning: homeland security system. Audio and video in use,” the signs say. “If, in fact, the man (Gannon) has posted on his property informing those who enter onto the property that they are being video- and audio-taped, that satisfies the two-party consent requirement in the state,” said Claire Ebel, executive director of the state American Civil Liberties Union.
According to police affidavits filed in Nashua District Court in connection with the arrest of family patriarch Michael Gannon, Karlis and Detective Thomas Bergeron visited the home at 11:20 that night to question a member of the family, a 15-year-old boy, about the robbery the boy was allegedly involved in. That night, Shawn Gannon, the family’s 18-year-old son, said his family watched and listened to the tape recording of the security system that monitors the front porch and back parking lot. He said they heard the detectives having a disconcerting conversation about how they would mistreat Michael Gannon. "We heard them pull up, and when they (Karlis and Bergeron) came up to the porch, they were talking about how my dad was a disabled veteran. Then we heard how they wanted to make him more disabled," said Shawn Gannon. "Detective Karlis said that my dad has been giving him a hard time for the past couple of days (with the investigation). And the other detective standing next to him said, ‘Well, why don’t you pull him out of the house and I’ll give you my billy club.’"
Meanwhile, the disabled veteran homeowner (an American… in NH no less!) faces two felony counts…
