How do you know that he wasn’t wearing colors? It’s not mentioned in the article.
Doing so when you aren’t a member will get you stomped.
In the 1960s, merely wearing a denim jacket with the sleeves cut off could get you jumped. That’s not how things are today but he certainly wouldn’t be wearing a Bandidos jacket/colors if he isn’t a member.
And when I said “colors” I don’t merely mean a red or blue “hoodie” as the crips and bloods are want to do. I meant wearing the patches of the group.
