The First Amendment guarantees freedom of association. This is an obstacle in enabling “common sense gang laws”. If New York treated the First Amendment like they do the Second Amendment then anti-gang legislation would include the following:
No new social organizations having more than seven members would be legal. Existing organizations of eight to ten members would be still be legal but no more than seven members could be in the same room at any one time. Existing organizations of greater than ten member would have the option of moving out of state or turning themselves into the police for Soylent Green feedstock.
