>>6781113wiki tells me that As a young man, Bigelow was repeatedly arrested on charges including aggravated assault, attempted kidnapping, criminal restraint, drug possession, robbery, and sexual assault. He spent nine months in the Albert C. Wagner Youth Correctional Facility as a teenager, and was later imprisoned for six months in Mexico City for illegally acting as a bounty hunter in Mexico.
This in itself doesnt cement him as a tough guy, however in 2000 Bigelow received second degree burns on 40% of his body while rescuing three children from a fire in Wayside, New Jersey. He spent 10 days in a hospital after the incident. Thats pretty badass and i'm leaning towards he was more of a a legit tough guy than most of the industry.
