In sons of anarchy what is an aryan shock collar?

In Sons of Anarchy, "shot caller" refers to a gang's veteran leader. It's the person who "calls the shots".

The term "shot caller" refers to veteran leaders of the Aryan Brotherhood also known as The Brand, one of the most elite prison gangs in the world. They are groups of white inmates that were formed in the California prison system in the late 1960’s.

While the exact number of Aryan Brotherhood members is not known, the gang has chapters in almost every major state and federal prison in the country. Estimates of the brotherhood's total strength vary, but nearly all exceed 15,000 members and associates nationwide, with roughly half in prison and half out. Learn more here.

In the news, TMZ has obtained an EXPLOSIVE document in the mystery behind Sons of Anarchy actor, Johnny Lewis' alleged love child, the birth certificate which shows Lewis was listed as the kid's dad.

After Lewis died on a murderous rampage back in 2012, his father filed court documents claiming Johnny had no offspring and therefore his entire estate should be divided amongst his parents. But TMZ has unearthed the birth certificate, which was filed in California and was also signed by Diane Gaeta. Check out more here.
