The New York Police Department (NYPD) is one of the most well-known and respected law enforcement agencies in the world. As such, their gear and equipment are highly scrutinized and often copied by other police forces. One such piece of gear is the NYPD riot helmet, which features prominently large shield numbers on the front. But just how big are these numbers? Some people have speculated that they are so large as to make the helmet cumbersome and difficult to wear.
