Wow -- that seems really odd; a GPS beacon seems like it is practically the definition of probable cause. I can understand police being reluctant to pursue crimes where the criminal is unlikely to be apprehended, but in this case it seems a straightforward way of boosting arrest numbers since the crime is so clear-cut.

Regulation and crimes are different things. Regulations are aimed at preemptively preventing potential crimes, usually fraud, by making parties affirmatively establish that they do not have criminal intent before committing an act.

Crimes are criminal acts -- we added an equal protection clause to the constitution to prevent exactly this scenario, where the police can discriminate on the application of the law. If the police are choosing to deny the protection of the law to a company like Bird then they are liable for a civil suit, in addition to violating their duties as law enforcement officers.
