Yep, it is called 2 deep leadership. Background checks have also been put into place. In my son’s troop as with all troops, there must be two men present at all times with Scouts (unless it is the dad’s son). The Boy Scouts have also instituted Youth Protection. It helps Assistant Scoutmasters recognize signs of abuse. However, as with most situations, it is impossible to insure that no problems will occur in a given situation. If a pervert is determined to become an adult leader in Boy Scouts, he will find a way. Sort of like seat belts in a car. Car manufacturers can install seat belts. But if a person is determined to drive without one, he will.
Dont confuse two deep leadership with no one on one contact.
Two deep leadership means there are two adults present at all troop level events, at least one of whom is BSA Youth Protection Trained and 21 years of age or older, and the other may be the parent or guardian of a scout present. The second adult can also be another BSA Adult Leader who is youth protection trained, but may be under 21. It does not mean that everywhere a scout goes when on a scout outing there are two adults present. There is also no limit to the number of scouts two adults can take on a troop level event, and one of the adults can be female.
No one one one contact means an adult scouter cannot ever be alone with an individual scout. Even scoutmaster conferences need to be held in open view, like in a quiet corner of a meeting room or off to the side during a camping trip.
Boys can still do day events on their own, like hikes and service projects, with no adults present. But patrol overnight camping is no longer allowed without two adults present, one of whom is a registered, youth protection trained adult.
