Would you let your 12 year old daughter walk to school alone?

Hello everyone,

My daughter has just begun school and unfortunately I am not able to drive her. I signed her up for the bus and it is about a 15 minute walk from home. I suggested that I can accompany her to the bus stop but she refuses and says that would be embarrassing. The walk is through several neighborhoods and I am simply worried for her safety. As I stated, she is only 12yrs. Do I let her go alone? Opinions?
