The Travelling Lindfields: But is it safe?

'Don't take a cab from the airport. Don't flag a taxi in the street. Don't walk anywhere after dark. Don't wander into the wrong neighbourhood. Drive a car in Peru! Are you insane?' I can't remember a time when we were so bombarded by safety warnings.  Guide books, the internet, other travellers, hotel doorman - everyone seems to have a cautionary tale and advice on how not to become a target in Lima.
