Criminalizes participation in criminal street gang.

This New Jersey bill (A 3661) makes it a fourth-degree crime to knowingly and actively participate in a criminal street gang while promoting or assisting others in committing specific violent or serious offenses. It directly affects individuals who knowingly help gang members carry out crimes like robbery, carjacking, assault, sexual assault, arson, burglary, kidnapping, extortion, or certain drug/firearm violations. The law defines a "criminal street gang" as three or more people meeting specific criteria (such as shared symbols, clothing, or prior criminal activity) and sets penalties of up to 18 months in prison or a $10,000 fine. The bill takes effect immediately upon passage.
