For periods, New York City has had to contract with the vandalism and defacement of public property caused by unauthorized graffiti. Amongst other attempts to stop the damage in December 2005 the city banned the sale of aerosol spray paint cans as well as broad tipped indelible markers to persons under twenty one years of age as well as prohibited them from possessing such items on property other than their own. By May 1 2006 five people - all under age twenty-one-had been cited for defilements of these regulations while 871 individuals had been detained for actually making graffiti artists who wished to create graffiti on legal surfaces such as canvas wood as well as clothing, comprised college student Lindsey Vincenty who was studying visual arts. Powerless to buy her supplies in the city of to carry them in the city if she bought them elsewhere, Vincenty with others filed a suit in a federal district court on behalf of themselves as well as other young artists against Michael Bloomberg, the city's mayor and others. The plaintiffs claimed that amongst other things, the new rules violated their right to freedom of speech. They inquired the court to enjoin the enforcement of the rules. Must the court grant this request? Why or why not?
