Thank you for asking for specifics on this case. Their "crime" was..."going against the mayoral decree currently in place," police stated" I agree with you that the governor does not have the proper authority to close down the private economy. I've reported several stories in Laredo, Texas and the main issue with the citizenry is their unquestioning obedience to authority and personal ignorance of civil liberties.
Usually, cases such as this one are cheered on by the local population. Rarely, do police officers get questioned over their abused of power. In the City Council meetings the council members were adamant about hefty fines, so that way people didn't question that stay at home order. The police were ready to follow any order. From the reports I've gotten from the locals they are going out of their way to inspect non-essential businesses to make sure they are closed. The perception of law & safety keeps people from challenging them. I had a friend who lives down there and runs a business. He told me that after the lockdown he tried to open shop to people who volunteered to break the lock-down. He has to hide his business' operation from the police. They sometimes come by and peer into his' gyms' windows to make sure they are not "breaking the law." The color of law is what shields them from any repercussions.
I hope this provides better context to this story. Thanks for your input
