BTS will soon be performing in the state of New Jersey at the MetLife Stadium, and fans are already preparing to camp outside.
However, a representative of the MetLife Stadium has stated that ARMY will be prohibited from camping outside the stadium. It seems that the most likely reason for preventing fans from camping outside is for safety reasons.
A while back, the NYPD had tweeted saying that they were just as excited about BTS performing in New York, but camping out in Central Park was not permitted. From the perspective of fans, it may have been a bummer but from the perspective of law enforcement, it could have been making their jobs much more difficult.
