As far as I know, they are illegal if people will not be doing that on a licensed cockpit,......
No, you can't apply that rules in the pandemic, not only cock fighting is not allowed but all sort of gambling as it gathers masses that would be prone to passing the virus among the people. So even if you do in a legal venue but the act itself is prohibited, you are still doing an illegal activity.
Agree, even the Vegas casinos, they were stopped for awhile although they are a legal entity, they only came back into operation when they are an approval to start operating again, if they operate prior to the approval, they are doing an illegal operation and they can be penalize for doing so, same with the example, cockpit owners can't used their license to exempt themselves from not following the mandate of the authorities.
