Someone would be doing Kristine a favor by pulling her aside and convincing her to drop it and move on. According to the official investigation her husband was driving more than 2x the speed limit on worn out tires. No one believes Roger was doing 55 or that the Carrera GT was/is "unsafe for its intended use." Roger's foolishness killed him and Walker, and it was completely avoidable. Pack up whatever family dignity you have left and move out of the limelight.
Agreed. It's terrible when you lose someone close to you and natural to want to blame someone else for their demise. That's when supportive but objective friends and family need to step in and help and not merely "tow the line".
