I think it's reasonable to be concerned but so long as they take common sense precautions, they should be fine.
Don't have mobiles on show, either in a hand or back pockets, as these young'uns do.
Be aware of your surroundings, especially when using cash machines or getting out phones and purses
Stay together
Politely but firmly decline offers of help to carry luggage, etc
If drinking in pubs, be aware of surroundings and don't leave drinks unattended.
Most of all, enjoy the experience as much as possible. London is a hive of experience, culture and diversity. So many lovely people and great things to see and do.
