This is about making his legacy to save lives. Reporter its still early, but for now a pennsylvania judge has ruled the suit can proceed. He points to a new jersey case where the court found the sender of a text accident is caused by texting, but only if the sender knew that the recipient would view the text while driving and thus be distracted.

Memorial day typically kicks off the start of the summer grilling season, but there is a warning that you need to know about before you clean the grill. Nbcs Chris Clackum explains why. Reporter whether you do it before or after a cookout, it turns out a good cleaning of your grill could present a bigger hazard than not cleaning at all. Researchers at the university of missouri who supplied some of this video say grillers need to be aware of the cleaning with a wire brush. Be aware the possibility that there might be a bristle in your burger. Reporter a bristle that falls off the wire brush, plants itself right on the grill and creates a serious hazard for grillers like matt hail, a husband and father of four. Thats the last thing i want is a metal piece to end up in their food and cause complications later on down the road. Reporter complications that doctors say cant be understated. One little bristle unrecognized could get lodged into various areas of the body, whether its in the throat, the tonsil region, in the neck region. Reporter or lodged further down like the stomach or intestine.
