A new gun law that goes into effect in New York on Thursday will require applicants for a concealed carry permit to provide a list of social media accounts for the past three years as part of the review process. State regulators will be able to browse the applicant’s social media posts to decide if a person has the “character” to carry a weapon.

The requirement was added because lawmakers said that previous mass shooters have sometimes dropped hints of violence online before they acted. The New York Sheriffs’ Association has called the rules “burdensome” on local government officials to carry out that part of the law.

Under the law, applicants will also have to complete 16 hours of classroom training and two hours of live-fire exercises. The law also creates dozens of “sensitive” places that would ban guns. They include schools, churches, subways, theaters, amusement parks, and even Times Square in Manhattan. (Fox 5)
