Phys.org / Data suggest 'red flag' laws are linked to sustained reductions in arrests

Individuals subject to extreme risk protection orders (ERPOs), or "red flag" laws, were significantly less likely to be arrested—including for violent and firearm-related offenses—while the orders were in effect than in the ...
