Barb Leland, 51, a newly hired clerk in the JCPenney juniors department, called security for the third time in three days Monday. 'There were these two teenage girls, and they were laughing loudly and pretending to talk to one of the mannequins,' she said. 'I just didn't want to take any chances.' Leland added that 3 p.m. on a Monday is an odd time for a pair of teens to be shopping.
