"Flying on holiday is as bad as stabbing someone"

[TAE]

UKIP: "Is flying to Spain the same as knifing someone in the street?"
Lucas: "Yes it is, people are dying from climate change"

the same as = as bad as = massive sharp intake of breath amongst voters (rightly so)

It seems to me that she meant: 'The flying of many people to Spain has the same effect as stabbing - people die as a result' .
