In another time and another place, this sort of behavior could get rewarded with a “Hero of the Soviet Union” medal.
I agree that “in another time and another place” this might be found to be acceptable , but this isn’t the time , nor the place to risk kids safety.
She alledged that there was no danger , except for the danger created by police. She preferred ideology to her childrens safety . The very fact that she stated the kids were in no dnager until the police arrived says it all !!
