No lawmen allowed
Another rule that most biker gangs uphold is that they do not let anyone who is associated with the law enter their gang. It doesn’t even matter if they were just a security guard, nobody that represents the law can ever be allowed to infiltrate the crew, it’s just a simple conflict of interest.
Bikers do a lot of vetting before they let anyone in, so if they find out that you have had a history in law enforcement, then it looks like you’ll be shown the door really fast. Even if nothing is going on there in terms of illegal action, you just can not be fully trusted like the rest.
