What is the test for a preliminary injunction against a person who admitted being a member of a criminal gang?

Under our general nuisance statutes, "[a] judgment prohibiting a defendant from doing that which neither past acts nor present intent indicates he is likely to do unless prevented by a court of equity, is an erroneous exercise of equitable jurisdiction." (People v. Robin (1943) 56 Cal.App.2d 885, 887, 133 P.2d 436.) The mere facts that a defendant "admitted" gang membership to a police officer or others or was seen associating with gang members or wearing gang colors or insignia, do not indicate that he or she has, or will in the future, engage in conduct amounting to a public nuisance. In my view, individual defendants may be subject to the preliminary injunction only if the City establishes a likelihood that it will succeed on the merits of its claim that he or she actively participated in the activities constituting a public nuisance, or had a specific intention to do so.

The City presented evidence of conduct by each of the named defendants in and around the Rocksprings area.
